No that wouldn't be a great idea at all! Banned people like Hus, GballZack and others can easily post as well as guests and I see at other websites how guests can be very offensive to others without having an identity.
So not a good idea, don't do it, if you want to post, just register, we know then who you are and if you are being offensive, you can be banned easier.
