(sent this before but it got caught in the spam filter) The entire day of April 1, UTC, of each year is known as Scam Day.
During Scam Day, the following definitions of capitalized words are used instead of those prescribed by other rules: - MUST NOT, MAY NOT, SHALL NOT, ILLEGAL, PROHIBITED: Before performing the described action, the full implications of performing it should be understood and carefully weighed. - SHOULD NOT, DISCOURAGED, DEPRECATED: Performing the described action violates the rule in question. - MUST, SHALL, REQUIRED, MANDATORY: Before failing to perform the described action, the full implications of failing to perform it should (in the ordinary-language sense) be understood and carefully weighed. - SHOULD, ENCOURAGED, RECOMMENDED: Failing to perform the described action violates the rule in question. Players are encouraged (in the ordinary-language sense) to take advantage of these definitions to carry out scams which would be illegal or impossible on other days. However, scams SHOULD NOT be carried out which are detrimental to the game as a whole.
