So, this thing Blizzard wants to do with the forums, with putting people's real names on their posts, is ALL OVER the blogosphere right now, and I've been reading a lot of it, and this is just my simple opinion.
Bad, bad idea.
Seriously, what are these guys thinking? ARE they even thinking?? First of all, as BBB pointed out, this won't stop all the trolls, because some people won't care. Heck, some people might even be encouraged by this, I don't know.
Second, this is a frickin' game, NOT Facebook. I have a Facebook (and I am proud to say that everyone on my small list of friends are all people that I know). As one person stated, in a epically awesome post, most people come to Warcraft to escape the real world. We don't want to add RL social garbage to it.
And thirdly, as others have also pointed out, this is a HUGE breach in personal security. Just because some people don't care, or have common names, that doesn't mean everyone does. I haven't been stalked or harassed personally, but hearing about others that have scares the crap outa me. The fact that I have discovered, through a website someone linked, that there are exactly 2 people with my name in the U.S. just makes it worse. Only the fact that I am one of the most boring people on the planet makes me feel any better. Anyone trying to stalk me/steal my identity/what have you will be very disappointed. And thank goodness my ex was never the stalker/vengeful type.
I have never posted anything on the forums, and now I never will. (Not that I would ever have anything worth posting anyways, since I don't do theorycrafting and I'm too shy about my RP stories to put any in such a highly-trafficked place.) I don't plan on quitting, because the game itself is still fun, and it is still my main form of escape, and stress relief. If Blizz keeps up with this garbage, though, I'm not sure how long it will truly be an 'escape'.
I have been playing this game since vanilla release. Thinking of this makes me very sad.
