Reported someone on facebook, they were automatically blocked, and now I can't unblock them?

I jokingly reported my friend for harassment when they put up a funny picture of me (which was stupid of me), and now it blocked them automatically. They aren't in my block list so I can't unblock them, and I'm not sure what to do? Any help? They didn't disable their profile, I've talked to them and they can't view my profile either.
