i kinda like the idea of this. granted, i think itd be complete bull for someone to just go around using because they are an ******, but, i cant stand gold spammers, and teh buggers were in game before friggin beta even opened up.
That's for someone just wholesale marking spammers. On the other hand, if you just do one or two of those you could (legitimately) claim you misclicked when you were trying to mark an actual spammer.
Sure, if you flagged 50 confirmed gold sellers and accidentally clicked the wrong person once or twice, I'm thinking they'd maybe just let you know to be a little more careful in the future and not suspend/ban you for harassment.
