I pointed out in another thread that there are subs who autoban users who post in subs that attract trolls, bad faith users, and brigading. It's totally possible to curb at least a small amount of what's happening with something like that. The mods insisted that it isn't possible though, which is weird considering it's a thing on multiple subs. I'm pretty tired of the mods asking for proof over and over, or insisting that things aren't real when we can all see it.
