Saying that all the problems at DV come down to ineffective moderation is like saying the Crime in East L.A. is due to police ineptitude. Trolls are creating the havoc at DV. Whether the mods could do a better job of smashing trolls is a completely different issue.
And to ask why Roger/Chinese Canadian/Erik and the rest haven't been banned...Ok, I'm going to say this very slowly for those who haven't been following the war...when an experienced troll who knows how to change IPs and use proxies will not leave you have 2 choices: ban an entire range of IPs in the hopes of crimping their style or hand delete each of their posts, providing there's a mod online at the time.
Either choice leads to whiney, ignorant little twats like you sounding off about either getting unintentionally banned or having to read troll filth when no mods are around. The bottom line is that the massive number of trolls at DV has made it a hell hole. The mods don't even want to visit, because all intelligent conversation has evaporated in the last couple of months. Who wants to be a baby sitter for no pay?? Would YOU like to moderate that shitstorm?? It's always the ignorant motherf*ckers who come up with the "simple solutions" to complex problems. The only solution to the troll problem at DV is war, and it's a war that in the long term in unwinnable. The trolls have a lot more free time, numbers and interest in DV than the mods do at this point. Game over, man. Game over.
