msk writes "Blizzard Entertainment has announced a deal with Facebook to tie Blizzard's upcoming Real ID feature into Facebook, making it possible for persons on Facebook to follow players on Blizzard games. The service is described as "opt-in", but Facebook is facing growing scrutiny over "opt-in" features apparently not being such. Real ID appears to be all-or-nothing, with little to no granularity of privacy control. In addition, friending a person through this service requires sharing part of one's login information, one's battle.net ID (which Blizzard previously advised, with good reason, never be shared), which is required to log into World of Warcraft and Starcraft II."
