Nextdoor app hands over IP and home address to marketers

Many residents of Moore Park have received mail from an organization called Nextdoor.ca which offers them a chance to join a neigbourhood information exchange. The sealed envelopes are addressed to Moore Park Neighbour with the precise street address and postal code. The letter inside assigns the address a six-letter code (RDDTMM for example) which identifies the address to the Nextdoor organization. One resident has observed that “the infrastructure appears all about tracking people right to their dwelling. There are data sets out there you can purchase that pinpoint users by IP address but not necessarily home address, this connects those two solidly. The minute you login with the code, they have your user-specific IP address, your machine, android/apple phone and/or other pertinent information. The more specific the information, the easier it is to market to you and track your preferences.” Nextdoor Says It Will Make Tens of Millions In Revenue This Year
