You're not doing anything wrong. The only reason these guys are pissed off is because the board is being "spammed" with your posts. HOWEVER, they're pretty good quality posts, which actually makes it okay. For some reason, that Dodgerson kid kinda ruined the reputation of repeated posts...

I kinda have an idea though. Why don't you try putting all your posts into one thread? And keep posting to the same thread under the comments? It's a little dumbed down from what you were doing before, but it'll make everyone happy. Including people who want the board clean (fucking anal-retentive retards), AND people who want to actually see content, especially *your* content. Don't leave!!!!
