Our (large) village had a schism in the local FB group!
Admittedly, we were all tempted onto it when 'Streetlife' sold out (literally) to NextDoorNeighbours or some such, where, to register, you had to provide far too many personal details; someone suggested we walked away from NDN and joined his open group, which many of us duly did, let's say 'Little Chuffington Neighbours'. Sadly, it rapidly became apparent that this was one bloke's vanity project; it truly got ridiculous, him blocking, deleting, 'turning off comments' every 5 minutes, and the endless jokey helicopter sightings, piss-take central- til someone pointed out an elderly resident of a local dementia facility had gone missing; someone hearing a airgun out in the woods one morning, so evidently a 'cat-killer' was at loose... and so forth.
In general, any dissent was met with the owner or his mates going 'It's his site, he can do and say what he wants', but many of us reminded them that this group had been set up as a replacement for StreetLife, but wasn't behaving like StreetLife
Anyway, a 'splinter' closed group formed, called 'Litte Chuffington Friendly Neighbours'- which is way better moderated, though it, too, is 'cat' central with a bit of Xmas Bin Collections thrown in!
