I know you've gotten your example, but I couldn't leave out the policy of our own Alpha Phi Omega.
This is a clause in the standard Risk Management Policy:
SEXUAL HARASSMENT/ ABUSE/DISCRIMINATION
The fraternity will not tolerate or condone any form of abusive or discriminatory behavior on the part of its Members, whether physical, mental or emotional in respect to sex, race, ethnicity, physical or emotional handicap, age, marital status or
sexual preference. This is to include any actions, which are deemed to be demeaning to all but not limited to date/gang rape or verbal harassment.
