RealID is Blizzard's new "social network" feature on Battle.net and games like Starcraft 2 and World of Warcraft. Unfortunately there are some privacy concerns with it, like your real name being displayed on the forums, or addons you installed in WoW able to broadcast your name to other players. Thus you might want to turn it off. Which Blizzard made artificially difficult. As you simply won't find the option to turn RealID off by looking at your account management page on Battle.net, here are the secret instructions on how to opt out of RealID:The trick is to pretend that you are an responsible adult and your account is played by a child. Thus you need to visit Blizzard's parental control websitem either the US version or the EU version . Assuming you haven't set up parental controls before, you now need to click on "No - Set up Parental Controls Now". Then you have to enter you Battle.net account name and password, plus the e-mail address from which you want to control the account as "parent". If you have an authenticator linked to the account, you'll have to enter that next.Following this, you will get an e-mail, which you should archive carefully somewhere. It contains the link to the real parental controls. Click on the link. On that site RealID might already be disabled, but if it isn't, uncheck the "Enable RealID" box. Select you timezone in the dropdown box below, optionally request a weekly play time report, and don't forget to click on "Save Settings".Voila, you have now turned off RealID. Good riddance!
