Nextdoor has suspended me numerous times. One for abbreviating last name for safety reasons I told them about. Other times when I chose humor over nastiness, but poster got butt hurt and complained. I see all kinds of ugliness on my Nextdoor. I've always been informative. Nextdoor can discriminate at will and there's no oversight. It can be so much more than a "have you seen my cat"? Site, but chooses to censor at will.
