This is basically Finnish employment laws with the serial numbers filed off. Except harsher -- the Finnish one suggests the accused person should discuss the issue and be prepared to apologize -- this says they should not defend themself, admit their wrongdoing even if the accuser was mistaken, misunderstanding, or malicious, and apologize no matter what, and (unlike the Finnish version) really emphasizes that the accused can be fired simply on the basis of unsupported accusations. I'm not sure who this is written for, but "a bunch of college freshmen in a dorm" seems to be closer than a team of collaborators on a game project. It starts with the premise that the people in the group neither know, trust, or even like each other. There are plenty of good codes of conduct out there. This is not one of them.
Added: One of the rules is no display of violent imagery. Um ... we write and illustrate games about murder hobos!
