MEE Mega evil empire

[JenMax]

I have seen seveal comments in the threads about the MEE, or "going" mee.

It seems this is a game score threshhold, which when a player goes above, resets the AI players to "hate" the MEE empire?

Is this correct?

tow questions, then. First, what is the score needed to trigger MEE status in a "stock" game of se4, and

Second, do all empires that cross the mee treshold become mee as far as the AI is concerned, or only the First player-empire to do so?

Thanks
