I don't doubt that the bad dynamics would happen regardless, but Facebook is just such a terrible way to have this group. First, it's private so you can't view any of it without joining the group which is a little icky though I guess they do that for moderation reasons. Second, there's just way too much content. I joined and it was producing multiple times the amount of content as the entire rest of my Facebook feed (which I otherwise keep to just actual friends and happily block people who post too much). And too much of the content is filler "look a train" type stuff. Having that crowd out actual friends' pictures etc wasn't worth it to me. I'd much rather have had it a subreddit I could occasionally go through and sort by best in the last month. So I left that group after a week for reasons largely independent of the problems talked about here.
