Nextdoor is a place where Karens and Kevins can be truly free. Since it's essentially a zip-code mitigated version of Twitter, most users are only here for a handful of reasons: their pet is missing, informal noise complaints, unofficial vigilante work, and the occasional good ol' fashioned neighborly grift. If you're not scamming your neighbors on Nextdoor, can you even call yourself a real grifter?
