What is StarCraft® II’s Add Facebook Friends feature?
Add Facebook Friends is an option that is available in the StarCraft II game client after selecting the Add Friend option. This feature allows your Facebook friends to find and add you as a Real ID friend on Battle.net. You can choose to not be included in Add Facebook Friends search results by disabling this option in Battle.net Account Management. Select Settings, then Communication Preferences, and uncheck the option Show my name on Facebook Friends lists under the Privacy section.
