What does motivate you to down-vote a comment?
Xichekolas: Things that are false, mean, or devoid of content (things like: "thanks!", "I agree", or "haha"). Only exception is things already at -1 or below.If a comment is none of those things and below one, I'll mod it up because I don't believe in burying someone you disagree with.As for things that are blatantly trollish (linkspam, racist, stream of curse words, etc), I'll gladly pile on until they are too faint to read... and usually flag them as well.
