re: Has anyone here joined Nextdoor for security purposes?

It can be a great place for communication. I joined during the great flood to get info and pics of other areas of my subdivision. Most of the posts are helpful and yes some alert us to security threats. I don't mind the extra notices because they are easy to weed out. The only problem I see is that it gives bad residents who are always stirring up mess another platform to be even more messy. Why can't we all just get along?
