Blizzard has come through with its promise of updated and more expansive options for its controversial Real ID feature, connecting Blizzard's games through use of real names as identifiers. The new options allow you to opt out of being listed in the "Friends of Friends" of other users, to deactivate the ability to be seen in Starcraft II's Facebook feature, or to turn off Real ID altogether.
To change your Battle.net privacy options, log in to your account's Battle.net management page and select Settings, then Communication Preferences.
Now all we need is an "go invisible" feature on Real ID, like most instant message clients have, and I'll be a happy Real ID user.
The full announcement by Nethaera is below:
Nethaera -- New Battle.net Privacy Settings
We'd like to make you aware of the new Real ID-related privacy options we've introduced to Battle.net. These options provide Real ID users with additional tools for customizing the service based on their preferences, enabling the ability to opt in or out of the Real ID "Friends of Friends" and "Add Facebook Friends" features or to turn off Real ID altogether.
Real ID offers an optional, convenient way for keeping in touch with real-world friends you know and trust, whether they're playing World of Warcraft, StarCraft II, or one of our future games. The "Friends of Friends" and "Add Facebook Friends" features provide you with even more options to stay connected while you play by making it easier for real-life friends to locate each other on Battle.net. You can easily enable or disable these features through your Battle.net privacy settings by logging in to your Battle.net account at http://www.battle.net/.
