Nextdoor: Where Privacy Is a Double-Edged Sword

Nextdoor logoWe routinely connect with friends everywhere on Facebook, Twitter and other social media platforms. But often, to our embarrassment and at a risk to our safety, we don’t know our neighbors. The hyperlocal site Nextdoor wants to return people to the good old days: When everybody knew who lived next door and down the block, or in the same building — the yesteryear sit-com world of Ralph and Alice Kramden and their upstairs neighbors Ed and Trixie Norton in Brooklyn. And there is great belief in the revenue potential of this folksy bid: To date, Nextdoor has raised $40.2 million, from backers such as Benchmark Capital, Google Ventures and Greylock Partners, on a valuation of at least $100 million.

Since its launch in October 2011, Nextdoor has connected people living in 14,000 neighborhoods across the U.S., adding an additional 60 to 80 neighborhoods each day, according to co-founder and marketing VP Sarah Leary, who notes that on average, Nextdoor neighborhoods have “hundreds of members” (the company won’t disclose its total national membership). While the connections on these “neighborhoods” start virtually, Nextdoor is designed to encourage members to meet up in the real world as well.

Nextdoor’s pitch is its members-only approach. As in, only the residents of a particular neighborhood can become a member of its Nextdoor digital equivalent. Non-members can’t even look at the site, much less participate in it, although the company has loosened up a bit to allow adjacent neighborhoods to connect with each other. The purpose of the privacy controls, Leary said, is to give member neighbors a “non-threatening way to share information” about things such as local events; school activities; recommendations for services like plumbers and babysitters; recent crime activity; upcoming garage sales and the like. Leary says that postings break down in representation roughly this way: 11% events, 22% civic issues, 20% crime and safety, 14% classifieds, 26% recommendations and the balance on various other topics.

To date, Nextdoor has done little to monetize its reach. Leary says that Nextdoor is putting most of its energy into building out communities and will begin competing in the $115 billion local advertising market when the network achieves critical mass. How big is that and when will it happen?

“We believe we will have reached critical mass when we have a certain penetration in a market. For example, in San Francisco we feel like we have reached penetration because 97% of the neighborhoods in San Francisco have adopted Nextdoor. When over 80% of the neighborhoods in a city have adopted Nextdoor, we feel very confident about that market,” she says.

But first, Nextdoor has some issues to sort out in whether and how much neighbors want to be walled in from other communities. In researching this story, I signed up for the service and discovered firsthand its power of engagement — but found its privacy walls a potential barrier to  connectedness throughout the Charleston community, where there are 19 Nextdoor sites and a few dozen others in the metro area.

To sign up, l entered my email address and postal address. Nextdoor informed me there was an existing site for my neighborhood of Radcliffeborough, which had been created about 45 days earlier. (If a neighborhood doesn’t exist on Nextdoor, a resident can create it and become its “Founding Member,” in effect, administrator). To confirm I was not an Internet troll, Nextdoor gave me three options for how I could be verified: By post card with unique code, phone call to a number registered to my street address in Radcliffeborough or credit card billing address matching my residence. I’m not sure, though, that Nextdoor’s verification process is any more secure than NSA contractor Booz Allen Hamilton’s. A friend who doesn’t live in Radcliffeborough was able to become a certified member of Nextdoor by claiming a neighborhood address that apparently wasn’t checked out.

I became Radcliffeborough member No. 30, and very quickly found myself getting more involved in the neighborhood, and getting to know residents whom I might otherwise never meet. Through Nextdoor connections, I learned about and  joined, Keep Charleston Beautiful, a volunteer group that has helped Charleston earn its “best city in the world” rating given by readers of Condé Nast Traveler.

Radcliffeborough has some “town and-gown” issues with adjacent and fast-growing College of Charleston, mainly having to do with litter, trash and housing-code violations in former single-family houses that have been  rapidly converting to off-campus apartments. This is a story that needed to be told in photos. So, accompanied by Radcliffeborough Neighborhood Association President Robert Ballard, I toured the neighborhood, and took about 10 photos of what turned about to be numerous problems at off-campus apartments, including trash dumped directly into the street, a third-floor balcony with precarious support and a tangle of exposed live wires strung to the side of a warren of apartments.

Imagining myself a 21st-century version of muckraking journalist Jacob Riis, I began putting together an illustrated article for Radcliffeborough’s Nextdoor page documenting all the problems. But I quickly learned that Nextdoor only allows one image per post. I wouldn’t be able to tell the story the way it needed to be told — in pictures that couldn’t be ignored or explained away.

But even if I had been able to upload all my photos, it dawned on me I wouldn’t be able to bring my article to the attention of the College of Charleston or the city government in an effort to get the problems fixed. Because of Nextdoor’s privacy controls, the only people who could see the post were other neighbors who were Radcliffeborough’s Nextdoor members (and one adjacent community). You won’t find a single Nextdoor post on Google or any other search site or in the world of social media.

Nextdoor is right to be sensitive to its members’ privacy, but when it erects virtual walls around each of its neighborhoods so they can’t use the site to address their issues to the appropriate authorities and the rest of the outside world, that, I submit, is going too far.

    And that is EXACTLY the biggest problem with Nextdoor. So many neighborhood issues are larger than the microhood. Silo’ing is a VERY bad thing for anything more than coffee klatsches and end-of-the-street pickup games. Our site is, after five years of community collaboration, read by local government officials who pay attention to problems and respond, among other benefits of having one community come together in one place. Issues that affect one microhood in our neighborhood affect most others. Even if you post a lost pet or a stolen car – it’s just as likely to be found five miles away on the other side of the peninsula as on the block, but if you’re just posting it behind a wall to the people close by, it might never be found.

    Our commenters even helped police catch a killer who was seen climbing out of a ravine hours later, and found three neighborhoods away. If the original spotter had just posted on his microsite “Saw a suspicious dude climbing out of the ravine,” the murder would likely remain unsolved.

    Oh, and as a bonus, we found out that a member of a local Nextdoor microsite was ripping off our reporting on a recent incident. Link to us? Great. Paraphrase? Fine. Steal copyrighted news reporting without attribution? I wouldn’t have known, since it’s not indexed, if not for a tipster.

    Tear down the walls. Unify neighborhoods, don’t break them down into siloettes. And as for impending ND advertising (mentioned in a Sacramento event this week)? They’re not getting $40 million for diving into SMB advertising. Like Patch, if they get anything, it’ll be Pepsi, coast to coast. Any corporate foray into neighborhood news/information is a bad one. If you want a neighborhood microsite, set up a real “blog.” Which among other things, will NOT limit you to one image. – Tracy

    I see a use for both.

    We have discussions in our neighborhood that we, certainly I, wouldn’t have written had it been something completely public.

    Like my Facebook page, many thoughts I want to share only with a select group of people.

    • TomGrubisich

      Facebook has three levels of communication: 1) among Friends (limited to them), 2) one on one with a specific Friend and 3) public (among all Facebook users and beyond). Nextdoor has only two levels of communication, both private: 1) among members of the neighborhood (and one or more designated adjacent neighborhoods) and 2) one on one between specific neighbors. What it needs is a third — public — level of communication, where content, including posts, can be shared beyond the neighborhood. For public communication, neighborhood members could still choose to keep all their personal information — except their name on a posting — private, as they now do.

      • Laura_Rich


        I fully agree. It’s a super easy fix, and potentially a category killer: Just add a “post publicly” function.

  • Matt

    Nextdoor app is very dangerous to our Republic…see Nazi collaborators

    • Aditya Belwal

      If Nexdoor app is dangerous for Republik then try Zipublik app for Android!

  • Frost

    I belong to a NextDoor due to my job and if it wasn’t beneficial to my job I would never go back. I have nicknamed ours “The Crime Blog,” because that’s all any of the residents want to discuss.

    There’s a lot of hand wringing, fear mongering and racial profiling. “OMG, has anyone seen the Asian girl walking, texting on her phone? It was 9:30 at night and she seemed suspicious.” “Alert! Two black guys walked past my house and they didn’t seem nice at all. I think they’re up to no good!” “I called the cops on two women going door to door. Turns out they were handing out religious literature, but I’m glad I called anyway.”

    I quit NextDoor last night. A landlady was having a grievance with a tenant, and posted a thread that this person is a terrible tenant–and don’t ever rent to him! She named him by name, said where he worked, (which turns out, she got wrong), and we told her to take it down. It was not just unethical, it was possibly libelous. I felt so sorry for this poor tenant publicly humiliated. Well, it was a back and forth exchange with her, then someone else chimed in and said “Enough already!–use private messaging, because apparently he/she didn’t want to “wade through” all the comments. I told them that they don’t have to read the thread. And I felt it was an important discussion to keep public, since this woman was publicly libeling this poor tenant. And that I was really disheartened by how close-minded he/she was being, trying to censor this conversation. Well, he flagged me. So I got flagged for THAT, but the original libelous landlady didn’t? I guess people only want to talk about garage sales, not important issues. Another landlord saw her post and agreed with me, and he resigned as well. This woman should have been moderated.

    • nextdoor sucks

      The one for our community lets fake people on there the Leads run the show and they are the worst people in our community!!!

  • nextdoor sucks

    The one for Riverstone in Alamo Ranch has horrible Leads they even allow fake
    people on there they don’t care they want numbers not residents. They even allowed a sex offender on there!!! Anybody want to get on nextdoor just use someone else’s address and anybody can get on there. All this was reported and shown to nextdoor and nextdoor didn’t care!!! Nextdoor doesn’t care about “SAFETY” that’s a joke!!! If you DARE use nextdoor you were warned, Watch out not a safe site at all !!!

  • Angela DeWree

    NEXTDOOR corporate has one official set of rules. However, the leads in each Neighborhood are given carte blanche to craft their own rules. Our actual “bricks & mortar” neighborhood is a remarkable living neighborhood of human homeowners. After too many solicitations from businesses, realtors, and the like from outside the boundaries of our real world neighborhood–
    and way too many angst ridden & derogatory posts from “virtual neighbors”– I finally quit the bogus online world of NEXTDOOR.

  • Really

    Unfortunately Nextdoor is just like any other business in that you have to have the right people in the right positions. Our community uses volunteers and has committees set up with members from each section to ensure the community it properly represented. The board of directors approves budgets and enforces deed restrictions.
    In our community, we use Nextdoor to keep an open communication with neighbors about events, issues and crime that affects our community. It is moderated by a small group of people with a head lead. The leads bring any issues they can not handle to the head lead and the head lead brings any issues that the board needs to address to the board.
    If there are issues that need to be addressed but are not within the purview of the board, then the head lead gathers the appropriate information and brings the issue to the right party.
    The system is not perfect but it allows us to ensure that everyone is treated with dignity and respect and that there is no personal attacks, campaigning or mass advertising. Each member that needs verification is verified according to their address as listed by google maps.
    If you use Nextdoor as a tool and ensure that the rules are followed and applied to everyone equally then the system works.
    In many cases about Nextdoor not working or the many issues that come up, it is more a concern of the people moderating the community incorrectly. If you are unhappy with your community, go to a board meeting and voice your concern, join the board and make changes, get involved but don’t point out the short comings of a few individuals as an overall problem of Nextdoor. In that scenario we should be mad at the Post Office for the 20% off Bed Bath and Coupons we get every week. We should be mad at the political party for a candidate sending out a campaign flyer.

    • Camera Guy

      Since when does an HOA use NEXTDOOR? Our board is so antiquated that half of them don’t know how to use a computer. When we served a couple years ago and suggested using social media you should have seen the cold shoulders on that idea!

    I discovered 3 days ago that the NextDoor site is sitting on top of a software “PLATFORM” run by a company Maponics (who is repackaging and reselling every bit of this information to Facebook, Google, etc.) READ THE PRIVACY POLICY ON NEXTDOOR. NEXTDOOR ADDS THE FOLLOWING TO THE USER EXPERIENCE: SERVER LOGS to collect data, WEB BEACONS attached to their website and emails to track your usage. They currently own NON-PUBLIC INFORMATION ABOUT EVERYONE APPARENTLY, ACCORDING TO THEIR PRIVACY POLICY. If you use Facebook Connect, these two services can and will cross-populate platforms given a chance to do so. SEE THE NEXTDOOR PRIVACY POLICY, PAGE 2, LAST PARAGRAPH: re: Facebook Connect.

    HOW DOES A COMPANY BRAND GO FROM NOTHING TO INTERNATIONAL in 3 YEARS??? If NextDoor was a startup, they would have to build infrastructure, test for stability on multiple browsers, build up security, create marketing plans and sales plans, and hire and sell. 3 YEARS TO INTERNATIONAL BRANDING…SEEMS VERY UNREALISTIC, EVEN WITH TONS OF MONEY AT ONE’S FINGERTIPS. BEWARE…NEXTDOOR IS NOT WHAT THEY SEEM.

    “In addition, neighborhood Leads can see unverified neighbors and their addresses and manually verify them. To further help with neighbor verification, Leads may also be able to see all neighbors’ addresses, regardless of their display settings. We may inform Leads who has joined the neighborhood.

    “We may notify the neighborhood Leads of your departure from the neighborhood and give you an opportunity to explain it to the Leads.”

    WOW, BLOCK NANNIES FOR ALL!!! I contacted a local real estate (Moss Beach, CA) agent name Trish McCoy regarding her setting up the Nextdoor website (she states she is the Lead and she set it up). When asked about the privacy policy set up by Nextdoor, she claimed she never read it, told me that the quotes I have printed here and from their privacy policy was NOT TRUE AND THEN SHE RESORTED TO IMMEDIATE NAME CALLING KNOWN AS CHARACTER ASSASSINATION FOR SIMPLY ASKING HER IF SHE HAD READ THE POLICIES AND UNDERSTOOD THE PLATFORM PART WHERE THE DATA WAS BEING MINED AND PACKAGED FOR SELL. She was upset for my asking her about Maponics and their policies and MS. MCCOY STATED SHE DID NOT CARE IF THEY WERE SELLING EVERYONE’S INFORMATION. She told me that she refused to view the privacy policy, so we ended the conversation.

    The professional backgrounds of the individuals at MAPONICS ARE VERY INTERESTING. It appears that they report their information back to EVERY CORPORATION UNDER THE SUN, and specialize in GEOSPATIAL INTELLIGENCE (see TIMM.PDF). There are over FORTY THOUSAND SITES UNDER THIS NEXTDOOR BRAND if you read the Maponics information, ALONG WITH OWNERSHIP IN MARKETS ACROSS THE GLOBE: They are integrated into Real Estate, medical, academics, emergency services, and probably many more not found, yet.

  • B. Smith

    Note: If you are non-member, the Nextdoor Privacy policy states that they can collect information on NON-MEMBERS and they MUST CONTACT NEXTDOOR TO HAVE THEIR NON-PUBLIC INFORMATION DELETED. TRY TO CONTACT THEM AND SEE WHAT SORT OF RESPONSE YOU GET???

    Nextdoor removed me for not allowing them to my full name by the way i was using my real name i just didnt want my last name spelled out fully due to identity theft and heres the end result…

    Thanks for contacting us about
    this issue. Both our Member Agreement and our Neighborhood Guidelines
    require that members use their real name on the site, and not an alias
    or abbreviation. You can read those policies here:

    Neighborhood Guidelines

    Member Agreement

    When a member reports that
    another member may not be using their real name, our Support team
    follows up on each report in accordance with these policies.

    While I can certainly
    understand your concern for privacy, at this time, we don’t allow
    members to abbreviate their last name for any reason. I’ve gone ahead
    and disabled your account for now. If you will consent to using your
    real name on the site, we will correct the name on your profile and
    reactivate your account. If don’t wish to use your real name on the
    site, let us know, and we can remove your account from Nextdoor.

      The same suspension of account occurred to us as well after we tried to complain about an actionable breach of state law which Nextdoor and its LEADS had allowed to go unchecked for weeks. Instead of dealing with the far more serious legal issue outlined in our complaint, Nextdoor suspended our account claiming I failed to use my “real name”. Read on for the rest of story.

      Quote: “ Hi Neighbor,

      I’m reaching out to let you know that the
      name you entered for your Nextdoor account, has been flagged by our system for
      not being your real name.

      Since we require our
      members to use their real names, I’ve temporarily disabled your account. I
      can reactivate it as soon as you let me know your real name. I will need proof
      of your real name and address in order to reactivate your account.

      One of the goals of Nextdoor is to create a
      safe, trusted environment where real life neighbors can connect with one
      another in a meaningful way. We believe that using your real name and identity builds
      trust and accountability and leads to more useful information sharing.

      I look forward to hearing from you soon.

      Best regards,


      The irony is that I have always used my REAL NAME but according to Nextdoor it didn’t match the name given to them by their LEADS. When I
      contacted the ‘LEADS” for our site, I discovered that one of the LEADS had listed her name as being the business sheowns! This “not real name” error has existed for over two years without being corrected by the Nextdoor Policy Police.
      Nextdoor has yet to apologize for their MULTI-YEAR failure of oversight of their LEAD’S behaviors.
      Nextdoor must apply their rules to THEMSELVES first. Nextdoor’s
      policy of empowering total strangers to become LEADS with unique authority to monitor the site they set up is fraught with problems. The integrity of any Nextdoor micro-site isby definition no better than the LEADS themselves.
      IMO, Nextdoor’s market integrity is a sham.
      In our case, Nextdoor’s clear failure to proactively monitor any individual website left the door open for libelous language to be posted without any oversight or editing from anyone. The LEADS simply aren’t forced to monitor the sight they set up, nor do they receive special training Nextdoor’s nebulous and ambiguous policies.
      When our complaint was ignored by the LEADS, contacting Nextdoor itself became a nightmare of finger pointing and abdication of their own demanded rules.
      Worse yet, the outcome of any action taken by
      Nextdoor in response to any complaint is a “state secret” according to

      Quote: “While I cannot share the details when
      we interact with other members, I am working on this issue and will take
      appropriate action, if necessary.”
      Best regards,

      Considering that our account is blocked, we
      can’t even monitor what changes MIGHT be affected by the Nextdoor Policy Police.
      The bottom line is that
      Nextdoor is simply one more “data mining hope we can sell the information to
      advertisers” internet nannycam which should be avoided at all costs.
      We will never use Nextdoor again for any reason.

    Actually whenever we are going to book for rental we should make sure about the privacy and security then after its all the responsibility of a landlord to do a tenant screening that will help him/her for getting a better tenant for sure.
