I cancelled my Nextdoor account in part because I got tired of all the paranoia and inevitable devolvement into political bickering, but also in part as a protest against Nextdoor that they need to police this kind of activity. It was only afterwards that I realized that Nextdoor wants this activity. Like Facebook, they see it as encouraging engagement thus traffic they can use to sell ads.

It confirms to me that cancelling was the right move for me but it also saddens me that we've gotten ourselves into a state in technology where the business model is to get people riled up and then profit from that discord.
