Regarding Rules: We do hand out warnings and bans for LQ posting and/or flaming. I suppose we could hand out warnings more but you can be sure we do hand them out.
Character Limit: There is a character limit and any posts that try to bypass it deserve a warning.
Threads: Done, until now this was never suggested...
Private Messaging: Done
Ban page: Under consideration but probably not going to happen. It wouldn't make the slightest difference because you cannot see their IP after they make a new account only admins can, and we don't have the time to check every single member.
Credits shop: There's already a Credits market where members can sell whatever they choose, this includes Netflix accounts.

Reputation: Yes, something does happen. We remove those reps (or at least I do) when they are reported via PM.
Marketplace: Ask the member that reviewed it to reply?
Suggestions: "it's sad to see suggestions that were made weeks ago not even noticed by the admins" I'm the only developer here and even I can't do everything as quick as I'd like to. I have finished MANY suggestions, I can't finish them all in the span of a day or even a week. I get to them when I can.
