We've got pretty much the same code of conduct here as Ancientsites does. The Ancientsites code of conduct states that:
"This community is intended to be fun, informative, and safe. CyberSites values freedom of expression on the Site, but not at the expense of others.
While you are at the Site and engaged in any form of communication, you agree NOT to:.
-Inhibit other users from using and enjoying the Site and Services.
-Post or transmit any fraudulent, threatening, abusive, libelous, defamatory, obscene or otherwise objectionable, off-topic or personally harmful information of any kind.
-Post materials in violation of another party's copyright or other intellectual property rights.
-Promote illegal activities.
-Promote discrimination based on race, sex, religion, nationality, disability, sexual orientation or age.
-Promote violence."
And the same rules apply here.
There is one added rule, however, and that is that no-one can post under the name of another person, without his or her permission.
Penalties for breaking the above rules include suspension or banning from the site, or part of it.
