I'm not sure why you're so scrutinous about this, it's a pretty basic feature. I've been watching the name for somewhere around 3 months, maybe 2 and a half, I haven't really kept track of the time exactly.
I'm not the one making the call to release the name, I am merely asking a GM, based on circumstantial evidence that the character (or possibly the account) seems inactive, if they are in fact inactive. And then, if by Warmane standards, they deem that name releasable, if then they would do so. I'm not trying to change the rules or steal names.
And by the way, I did get a pretty quick response saying that they don't do it by request, and that it seems like names are released in waves when they clean out inactive accounts or characters (whenever that might be, I don't know). I'm fine that they don't do it, I just wanted to know.
