Also you can add

AllowPlayerMessages = No
AllowAnonymousMessages = Yes?

And advanced paranoid level:

CPEnableRaceName = No
AllowShipNames = No

I will add these for a truly anonymous game.

But, currently, the server is very talkative and it makes no sense to disable in-game messages when you can as well click at a username on the game page to send a PM. Disabling that needs a major coding effort.

These settings make alliances harder, but do not completely disable cooperation. No game setting can disable cooperation (even with disabled messages, I cannot prevent two players to team up by mail "let's join this game, look what races we get, and then cooperate").

Unlike the previous games, this one has the written rule "no alliances" and I (and most players who join, probably) expect this rule to be honored, even if not enforced to the last bit.
