In the last month, on NextDoor, they doxxed and banded together to get the mentally-challenged skateboarder who’s been my neighborhood for years, and had him arrested because a user felt threatened by him standing around the neighborhood shouting obscenities during manic episodes. (He’s now in jail and this NextDoor thread is trying to make that permanent.)
And today there is a discussion and petition to end the Sanchez slow streets because they are “dangerous” to children and bikers due to cross-traffic and somehow “driving down property costs.”
I suppose all of that can be found on whatever social media site you choose - Twitter, Facebook, etc. But it seems extra pervasive on NextDoor, and I think the internet would be a little better off without the platform as a whole.
