SaveTheWorld:Terms of Service
What you CAN'T do is what you wouldn't do anyway
Rules (that are conditions of participation) are simple and short:
Nothing irrelevant allowed! Profanity, advertisements*, or other spam will get you instantly banned. Personal attacks (as opposed to relevant "criticism") will be deleted and you will receive a warning, or the attack portion may be greyed, if they seem marginally relevant to the discussion; if they seem mean or gratuitous, and are the whole substance of your content, you will be banned. Contributions only marginally on the subject of an article or a subheading will be deleted. Or perhaps moved if an editor finds a place where they are appropriate. The only time it is relevant to attack the character or qualifications of a person rather than the merits of an issue is when the person is the issue: for example he is a candidate for public office. But even then, unsupported criticism is a "personal attack".
That's about all that you can't do.
(*Actually we will allow a bit of advertising, in your personal page, limited to a 25 word description and a link, provided the link is to a legitimate product or service that you provide and not to subjects rife with fraud, lust, and spam.)
What you CAN do is described at Rules.
