I lol'd.
EDIT: They found out everything about the guy. Thats kind of scary. :/ But I don't use the official forums, so...
All to wowhead's forums!

I bet this reveals that 90% of the female avatars are played by males. I'm not hating here, as one of my characters is a female.

There will probably be a few people who find out the 'woman' they have been having teh sechs with in WoW is actually Big Kevin a truck driver from Barnsley.

Ah, the memories.

As a troll reduction policy (not the Warcraft race), it may seem like a decent idea, but all it will do is make people afraid to speak their mind. The trolls will still be there, only Blizzard will be arming them with your "real name" for the rare crazies to make use of. Less privacy and less freedom to bring up the occasional difficult subject, seem like a bad way of dealing with the immature.

Think of all the potential stalking and spying people could do. That's scary with the nature of some people who are online. Death threats and harassment would have to be taken very seriously otherwise victims could be in danger.

Bingo. Thirteen year old fuckwads trolling the forums aren't likely to care if random people know their name. They're probably not going to have much of an offline presence, so they're still effectively anonymous. Meanwhile the folks who have built lives and careers that are associated with their full name now have to worry about the aforementioned fuckwads causing problems for them offline as well instead of just occasionally giving them grief on the forums.

Everything I've read so far says it IS just for the forums and for billing purposes

Of course, it was originally just for billing purposes. Then suddenly it's for billing purposes and forum use. Next it will be billing, forums, and whatever else happens to strike Blizzard's fancy. Of course, tying subscription billing information to forum accounts should have been a red flag for everyone the moment that was done.

Sure, that;s how it's going to start. But where will it end? Will they then require you actually divulge your geographical location? Perhaps first with country (not a huge problem on its own), but then what about state/county/prefecture then later city too? All of which they already currently have for "billing purposes" but could very well decided is required for forums when they realize that demanding names hasn't stopped trolls in the least bit.
The more worrying thing here is that if they get away with it, who's going to be next to follow suit?

Even BBC knows about Blizzard's failed experiment:
http://news.bbc.co.uk/2/hi/technology/10543100.stm

Mr Brand said that one Blizzard employee posted his real name on the forums, saying that there was no risk to users, and the experiment went drastically wrong.
"Within five minutes, users had got hold of his telephone number, home address, photographs of him and a ton of other information," said Mr Brand
The post and topic has since been removed from the Blizzard forum.
That "failed experiment" of posting his real name, reminds of something similar in the UK when some TV personality, I forget who, stated that there was no such thing as identity theft or the like and happily published all his information. Only to then find that someone was able to use that information to gain access to his bank account and remove a sum of money.

It's just plain unacceptable in the end. Should Blizzard not be willing to respect my privacy, I find that my willingness to part with cash will be hampered. I really did like Blizzard, and I didn't think they could do anything too majorly stupid.
This is just.. surprising. Who in the higher-ups thought this was a good idea? Did anyone raise the concerns the community has?

What I find amazing is what we (gamers) will accept (DRM) and agree to (revealing full names) . . . just to play a game.

That is epic. Unfortunately, it's probably not enough for them to call off the whole charade.
