After reading a few pages in this thread, I have something to say.
Trolling is not about being negative, or about being a fanboy. It's not about showing how other people are wrong. It's not even about taking threads a little off topic. It's about continually trying to ridicule others with insulting posts. That's it. If you think that trolling is about continually trying to get a rise out of somebody I have bad news for you. Virtually *any* post can be viewed in that manner. It's entirely subjective, and that sort of view on what trolling is leads to a witchhunt.
I've never had a problem with Kerotan. Rol is one of my favorite users on the site, because he's not afraid to speak the truth. There's only one or two people on this site that I genuinely think are trolls, but even their trolling is not severe enough to bother reporting to the mods.
TL/DR stop the witchhunt. Ban people for being continually insulting to others. Not for speaking their minds.
