I thought they said they were going to investigate reports before silencing someone. I guess it isn't the first time Blizzard lied. I like the idea of the system but if people are going to be abusing it then they either need to get rid of it or actually look at the reports.
I'm wondering. Can someone get silenced by not even saying anything at all? What if some douchebag (which there are a lot of in WoW) decides to report you for no reason other than to be a douchebag and you didn't even say anything?
