A post is considered defamatory if it undermines someone’s reputation non-trivially with lies or unproven statements of fact. This does not include statements made in good faith, with an honest belief in their truthfulness, or with the consent of the person being described. Obvious jokes and other humorous expressions are not considered defamatory regardless.

This rule exists mostly to ensure discussions do not turn into a series of unsubstantiated personal attacks, even if made in a manner which is on the face a suitable tone for the discussion. If you are to make negative claims about other people, you must be able to substantiate them with evidence.

Linking videos, images, or any other content which is illegal (eg piracy or drugs), not suited for a younger audience (eg shock content or pornography) – a population which is generally not unprevalent in NationStates – or that may otherwise damage a user or computer is strictly forbidden. Linking sites where one can access such content is also prohibited.

Joking about, exalting, or defending tragedies and atrocities (especially genocides) is strictly forbidden. The same applies to joking about or exalting the perpetrators of such atrocities or the ideologies behind them.

Spam is “irrelevant or unsolicited messages sent over the Internet[...]”. Recently, this rule has been applied more broadly than how it was in the past to appropriately react to increased amounts of spam-activity. The Moderation Committee, generally, stays strict to the rule's definition and considers the repetitiveness of the action merely as aggravating. Although players are encouraged to discuss freely, at the same time the constant search for attention through posts designed solely for this purpose is, as of now, generally regarded as spamming.
