Make posts visible only to those within 2 blocks, or around 150 households who are close neighbors. Why 150 and not 1500 or 15000? Dunbar's number. https://en.m.wikipedia.org/wiki/Dunbar%27s_number
Okay so if Nextdoor serves content to local communities which have cultural norms varying from the bay area to so called fly over states how should they monitor their moderators?
If this is such an issue for you please describe how you think a platform which you describe as "fine." should moderate posts across a country as diverse as the US?
