I haven't been here that long, but I will only report spam and really insane racist/homophobic comments (which I haven't seen). I just don't get how people get so offended over faceless people... online.
Oh come on. This site is nothing but back and forth. You say cats suck and 7 times out of 10 times you'll see flame wars over how dogs are El33t and how the poster is a noob.
And this goes for other sites, too. This is a public forum. When someone blast me or doesn't not subcribe to my ideas, I'm going fanboy on 'em.
