Hello, starting with the subject of your message, it conflates two completely unrelated concepts: a social contract, which is a "mission statement" and statement of the general principles of an organisation, as well with respect to the inner workings as well as an engagement to the outer world; and a code of conduct, that gives rules about expected behaviour in a given context (conference attendance, mailing list postings, and so on), as well as a procedure that can be followed if the rules are broken.
If you start by equating two unrelated concepts, nothing useful can come out of a discussion. Andreas
