Not really, some members will go off on someone for disagreeing with their personal oppinion. A personal oppinion is as valid as yours, as its you OWN oppinion. If you dont agree fine, you can state your points, but to curse someone because they think Matt Hughes is better than GSP is wrong.
Neg reps are fine, neg repping because you disagree with what someone said even though it was their oppinion and put across fairly is wrong, or because they slated your fave fighter or just cuss your a "internet hardman that can neg rep" is wrong. But for them you can PM a supermoderator or a PM and find out who did it and i guess get it taken away.
