Or by anyone using his "ignore list" thing. Sure there's a lot of trash out there, but this guy is a nutjob by ignoring that much people, just to think the effort it took to ignore that much people is way more annoying than just ignoring the posts you don't like. Statistically a lot of people is being ignored thanks to that list that are posting decent stuff. Also it doesn't take into account people get better, overtime they learn and start posting more sound stuff.
So please stop ignoring people randomly, stop judging people on their signature and whatnot.
look at his rank and then look at your rank.
your ignorelist will grow with time
