You've misunderstood me, no one is being excluded and there's no real name policy. Use a pseudonym, make two accounts, make ten or a hundred if you like. What you can't do is use the app to prove that you really are John Smith, if you didn't sign up as John Smith. And to the extent that one of the main features of the app is to prove your identity, the app would not be useful to someone who doesn't want to do that.
