CMLKevin and PermaWhite Cheater red and pink are cheating as they are controlled by the same person

pink did not send an alliance email and form an alliance with red, but never attack red and also help him get techs

public accusations of cheating are very explicitly against the rules. If you are concerned about a cheat I would suggest emailing the game dev. Doing it this way is likely to only lead to you getting a reprimand.
