EDIT: a code of ethics is a very good idea, the only problem is, it's only ethics = it cannot be enforced. Why don't make it rules for every mafia game with the possibility for the host to permit exceptions? Every mafia host begins or ends his opening post with a link to the "general rules for every mafia game" and points out the exceptions on the general rules: for example: "in this game, it's allowed to quote pm's". If you make it "rules" like in "forum rules", the moderators have the possibility to send warnings to those who violate them, making it more likely that people will obey these rules.
5 posts a day for the living would remove the ability to debate. I don't think the dead should be able to debate, just state an opinion once in a while.

As for your edit:

In general I think it's better to enforce the game rules within the structure of the game itself. Violation of rules = WoG, banned from future games, etc.
