Multiaccount problem

Hello, in my current Christmas Event game nr 4549042 there are 4 or 5 nations lead by same Indian guy. They are only active in same hours and attacked me even though I am far away from them. And it is a deathmatch game.

Even their nicks suggest same person giving names.

Well, game is over for me, but honestly if this happens more often it is pointless to play this game. Mods could try to catch them and ban ASAP.
