Why do I keep getting 30 day bans on Facebook?

[john]

I can't like, comment, add friends, respond to messages, it's really annoying. The only things I can do are update my status and share things.

I don't send out friend requests at all, I don't spam anything, I don't "like" things too much, I'm not abusive and never post inappropriate stuff. I don't do anything, basically all I do is comment and send messages to friends, I also manage a couple of pages (even more frustrating is that I can only post and I can't respond to my fans when they comment). Facebook thinks my account is fake. They're sort of right, I don't use my real name (though I do use a real-sounding name) and information for privacy reasons but I still want to be able to connect to my friends, which I know in real life and I tell them where they can add me. I keep having to verify by email and cell phone number and I still get the bans. I'm so frustrated, I'm thinking of just making another account or quitting Facebook altogether.
