That’s fair. It depends on the communities. Places like Tumblr and Pics had effectively no moderation which left the entire place just a shithole. But then you had places like WorldNews and StarTrek where the mods became specifically known for stirring shit and causing a boatload of problems. Hell, one particular moderator of StarTrek is the reason that so many other communities splintered off.
For me it was a lot of heavy handed moderation. The lack of moderation was frustrating too, don’t get me wrong, but I guess the communities I was most active in were ones where people were constantly pointing out how the moderators were terrible people.
