We already have a known cheater in @trinhlan in 2nd on the FFA leaderboard. If it is true that these two are also cheating, which looks likely considering the screenshots of the play, then that makes three cheaters on the leaderboard. Which is just sad to see with the mods not taking any action.
Fake accounts plays FFA like a team game

Thanks, @rolandtaverner. The second screenshot is the game that I was talking about in the main page.
At the moment I thought it was a one-off and accepted (veeery bitterly) the defeat, but when the same strategy repeates itself over and over again is clear that is cheating.
I hope that the mods do something about it. It looks pretty obvious in my opinion.
