I play on an RP server. One of the reasons for this is the naming policy that requires players to at least try to create an atmospheric name.
I don't report a lot of names. But when I do, in the past, I have seen action taken. However, recently there has been a character that, though reported several times, continues to keep his inappropriate name.
I won't name him, but his name is a sentence along the lines of "ILoveBeansAndRice" or "GiveMeABanana". A full sentence, rather than a name, you get the idea.
But despite reporting, his name persists, week in, week out.
Does Blizzard still enforce the RP naming rules? It'd really annoy me if they don't. But I'd rather know than waste my time and theirs with meaningless reporting, if they do not.
