Here are some pertinent parts of the TOS:
Topics of Discussion
While these discussion forums encourage a wide range of opinions, please keep your posts focused on the topic of the forum in which you are submitting your message. Each forum has a different topic, so what is appropriate in one forum or thread may not be appropriate in another. Generally speaking, however, profanity, vulgar language, and personal attacks are not acceptable in any forum.
Inappropriate Language
The use of inappropriate or offensive language is not permitted in these forums. Inappropriate or offensive language includes, but is not limited to, any language or content that is sexually oriented, sexually suggestive or abusive, harassing, defamatory, vulgar, obscene, profane, hateful, or that contains racially, ethnically or otherwise objectionable material of any kind. We ask that you please be considerate to other members in the forums when posting your messages.
Harassment and Flaming
The Student Doctor Network members are not permitted to harass or "flame" other members. Please do not post or transmit any unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, profane, hateful, racially, ethnically or otherwise objectionable material of any kind, including, but not limited to, any material which encourages conduct that would constitute a criminal offense, violate the rights of others, or otherwise violate any applicable local, state, national or international law. Please note that this also includes the posting of taunts on a forum solely for the purpose of deriding that forum's topic and/or members.
Other General Rules of Conduct
You shall not post on these forums any Content which (a) is libelous, defamatory, obscene, pornographic, abusive, harassing or threatening, (b) contains viruses or other contaminating or destructive features, (c) violates the rights of others, such as Content which infringes any copyright, trademark, patent, trade secret or violates any right of privacy or publicity, or (d) otherwise violates any applicable law. You may not post on these forums any links to any external Internet sites that are obscene or pornographic. You shall not use the main forums for any commercial purpose, to distribute any advertising or solicitation of funds or goods and services or to solicit users to join competitive online services.
Banning
The Student Doctor Network reserves the right at its sole discretion to restrict, suspend, or terminate your access to any part of these forums. If you violate any of the rules stated in this document or any other service terms documents, a moderator will remove the offending message and send you a note letting you know why the message was removed and requesting that you adhere to the forum policies. It is your responsibility to maintain a current, valid email address in your registration information so that our moderators can contact you in the event of a policy violation. Any member who violates our policies three times will be denied access to these forums for a period of 30 days, whether or not they were able to receive a message from a moderator stating the nature of the violation. Any member who refuses to comply with the policies of these forums will be banned permanently.
