It's not like any of the other posts are actually saying anything anyways. I mean, c'mon "Anal Pudding"? The actual post just said "Yum" and had a smiley face, and you're complaining about Johnny Rotten's posts? Maybe it's because they're a different kind of pointless...
The first bad rep I got was from this forum and it said "You'll soon learn this isn't a very hippie place" So I'm guessing that there's already enough hate here and he isn't really doing that much damage...
You go to your control panel and it shows all the rep you've got. --EDIT-- And apparently you're accumulating bad karma...not that it really matters or anything. I'd turn mine off, but I'm too lazy...
