Blizzard's Real ID system, whereby users could share an account over several services using their actual name, seemed like a good idea to some, didn't exactly go down too well with many others.

Now those who first thought it was a good idea, and now don't, can get rid of it, with Blizzard revealing a means whereby users can opt in and out of certain Real ID elements (like Facebook compatibility) or in and out of Real ID itself.

All you need to do to make the changes is change the settings in your account.
