It's not gang rep. Everybody didn't get together on Skype and say "lets all negative rep him!!!". He is a terrible spamming member and deserves all his rep. And he is even getting useless positive rep but thats a not problem, right?
I've seen exactly what you just said be done before but on another forum. I'm not trying to stick up for the guy if everyone actually thinks he deserves it, I'm just pointing out a possible problem.
I never said I care about how much people on the internet likes me. If I did, then I would be an asshole to a lot less people. I am stating the fact that everyone uses rep to show only how much they dislike you.
