said by Noah Vail :

However, AT&T may immediately terminate or suspend all or a portion of your Service, ... for conduct that AT&T believes (a) violates the Acceptable Use Policy; or ... a violation of these TOS, or any applicable policies or guidelines.

So an AT&T user can be kicked off for violating a non-disclosed guideline, instead of a revealed policy.

AT&T comes out of the closet the same way Larry Craig does.
