I found the USAWKF rules on their website. PLEASE tell me you weren't referring to these rules.

Using prohibited techniques, including:

Strikes to the back of the head, neck, throat, or crotch
Elbow or knee strikes
Striking opponent's head continuously to deliberately injure opponent
Use of excessive force to cause opponents to fall head over heels off the platform
Attacking a fallen opponent (except when an opponent falls deliberately as combat technique).
