Recently, as in this morning, Blizzard announced that with the launch of Starcraft 2 and World of Warcraft: Cataclysm that they would be launching new forums that required the use of real ID. This means all posts, including those by Blizzard moderators, will be identified with a real life(or possible fake, but I'll discuss that later) name.
As you might expect, there has been a lot of debate since the announcement, including a 156 page(172 once I finished this post) long thread in the North American WoW forums.

Is this not exactly what everyone tells you not do to on the internet? The given logic behind this decision is that if people are forced to reveal who they are than they will make higher quality posts. I agree it will probably reduce trolls a little, but just look at Facebook/Myspace to know people still troll when their identity is known. Which also brings me to the point, unless Blizzard is going to require people to link a credit card or some other form of identification with your account then you could easily just create an account with a false name.
To me, this seems like a great way to drive away a large portion of the community while also opening up an easy avenue to real life harassment.
