>>1 easy, Admin take note:
1.Stop blacklisting TOR nodes.
2.Stop frivolous bans, just because you got trolled. Don't reply to trolls.
3.Create some interface for quickly moving threads to their boards(like in FrozenVoid bbs, each thread belongs to its own specific forum, almost nothing is offtopic).
4.Stop referring to your users as retards, being a "lone genius" and a couple of shitposters tolerating you isn't a recipe for successful bbs.
