I went looking over there.There is a page with the forum rules here: http://myidol.americanidol.com/whatsthis.aspx?m=rules
It says:
If one of your posts is deleted, it is usually because you have violated a forum rule and the deletion is a warning. If you establish a pattern of violations, your account may be flagged. If your account is flagged, you may get clarification by writing to Stevo ( stevo@prospero.com ) and you may be reinstated if you agree not to create further violations.
