Google's horrible new policy on using real names in Google+ effectively means that the service is now a danger to real people. You have to ask yourself why a company that pledged to not be evil would do this.
Google has said that if you don't "use your full first and last name in a single language" you're in violation of it's terms of service. If it flags you, you'll have four days to change it or it'll boot your ass. You can't use initials (even that's what you go by). You can't use a pseudonym (even if that's what you go by). And you can't use numbers or symbols (even if they are part of your name).
