Here is the rule that applies to the Orange Papers link.
2. Outside Agendas: No posts of an overtly political or religious nature OR posts promoting advocacy of particular personal, medical, legal, religious, political, or non-profit causes. The forums are intended for offering mutual personal support related to recovery from addiction or recovery for family and friends. This is our primary purpose. Debating controversial subjects should be taken elsewhere. Limited references are allowed, but the forums should not be used to convert others. Do not post content or links to and from sites that flame someone's person, religious beliefs, race, national background, sexual orientation, or recovery program/method. It is inappropriate to promote the use of alcohol or drugs on our addiction recovery forums.
