At one point a couple years ago I had several super popular threads going about how to fix battlegrounds, exactly what changes had caused BG PvP quality to deteriorate and PvP guilds to become almost non-existant, why my system would be 10x more fun, exciting, and positive than a rating system and would bring back PvP guilds and the feeling of camaraderie of the vanilla PvP community, and specifics of how Blizz's then current plans to rejuvenate BGs would fail (they eventually abandoned those ideas). I had a couple thousand replies, about a third of which were variants of "Blizz, hire this guy, NOW!" Which is frankly incredible given 90% of replies about PvP are of the "LOL, ratings" variety. Even the biggest trolls ended up in full support...
Then one day I logged on to discover I had a forum ban for "insulting a fellow forum user" and every post / thread I had *ever* made (going back years) had suddenly vanished. Every post, every thread, every reply that other people had spent time and effort on, gone. Not locked, just totally gone.
Yeah... lesson learned: Fuck WoW.
