RealID -- Unethical and Dangerous
The RealID changes to Blizzard's official forums are unequivocally unethical and potentially dangerous. The community response on their official forums -- as well as nearly every fansite -- is huge and overwhelmingly negative.
Blizzard's stated goal is to help reduce trolling on the forums. The idea is that when a poster has an identity they can't escape, they're less likely to threaten their reputation. Their other, less-discussed goal is the creation of a Blizzard-owned Facebook which they can directly monetize and which can also provide an advertising platform for future games.
They're doing this entirely at the expense of your personal privacy. If you want to use a service you had used in the past, you now have to be willing to post your real name to the public alongside every post.
Here's where the problems are:
- Employment -- Posting to Blizzard's forums will now show up for any employer doing a search on your name. Given Blizzard's search engine rankings, you can bet this will be pretty high up on the list of results. No matter how unfair, many employers will look on this negatively.
- Women -- Many women playing the game choose to conceal their gender to avoid harassment. Whether fair or not, posting publicly with their real name will not only be uncomfortable for some but could very well lead to direct sexual harassment in and out of game.
- Minors -- Any parent will need to be far more concerned about their children's activities on Blizzard sites than they currently are. This is especially true in any case where a child's real name can be found or their address can be tracked.
- Uncommon Names -- Anyone with an uncommon name can much more easily be tracked.
- Security & Hacked Accounts -- Blizzard is not doing a good job safeguarding accounts. If they have another breach in their account system, it won't matter how clean your own computer is -- a malicious user could be posting under your name, leaving a permanent and damaging trail.
This move probably will get rid of trolls. It is certain to get rid of a lot of good posters, too. Unfortunately, the forums are also one of their main avenues for both customer and technical support, and users are often redirected to them even while on the phone w/ those departments.
You will never see another post from me on their forums. I've already given my name out via other platforms, but those were my choice, and those were done in a setting where I can completely control how a potential employer views it. I know a number of other good users who are being faced with this same decision and coming to the same conclusion.
You don't need to be a security or privacy rights advocate to understand how bad this can be for you or your friends on a personal level.
