Are we forbidden to criticize moderators?

Today I made a post agreeing with those who criticized Dynasty and mysteriously my account was deleted from 2+2. I have had to reregister. Is this normal practice for 2+2 to delete the accounts of those who criticize moderators, or just the practice of those moderators who can't take a little bit of criticism and are on a power-trip. Talk to you all later after my account gets deleted again.
