After some time for thought and after reading the arguments of others, I began to rethink my initial position. There are several special cases where having a real name linked to a fantasy world persona could be harmful. Teachers, LBGT, celebrities, or anyone who is dealing with a stalker could be at risk of losing their jobs, their sense of security, or simply peace of mind while trying to unwind. This may be a small portion of the gaming community, but that doesn't diminish their concerns.
There is great potential for abuse in such a system, and the premise that real names will increase accountability is inherently flawed. In my own message to Blizzard on the issue I said:
I work at an online moderation company, and a few of the accounts we handle have us moderate Facebook pages. Real names are all over the place there, but I can assure you from experience and a healthy use of my delete key that there are plenty of trolls despite being stripped of their anonymity. Real names don't keep people from being nasty, rude, crude, spiteful, dangerous, and hateful there. They won't keep it from happening here.Real names alone are not a solution to increasing accountability, and they're certainly not worth the price of loss of privacy in this particular situation. It was with great relief that I saw this morning that they had put further thought into the situation and rescinded their decision. The other tools they proposed at the same time should be sufficient. Threaded comments threads will give people a direct line to those they wish to speak to about their online behavior without feeling they will be lost in the din. "Karma" points can be used to let even socially inept people know if their posts are well received. Yes, I've seen such systems abused in past forums I've participated in, but the current forums frankly can't get much worse.
That doesn't mean I don't think there's a time and a place for using real names to ensure accountability. I just happen to think that an online game is not the appropriate place for it. There are better ways to combat trolls and encourage greater accountability online in such an environment. Every case of online moderation is situational and the environment must be looked at within the context of the user base in order to understand how best to combat undesirable messages.
