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.

Don't waste your time. It's not a poker tournament with a prize pool of several million.

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").

You're absolutely right. Exactly this I had in mind when I said that game with anonymous players is not a panacea.
