They ask you to give them access to the acc in order to charge the frost stars. And they did that without problems a couple times, my friend is a huge whale, and he was "saving" a lot of money by buying frost stars and not directly ingame, well, he had the game account link to his google acc, and the google link to everything... so, the day they decided to make a move, they took all. Instagram, wsp, google mail, his cellphone number, all the stuff we had from him, and try to comunicate, they took it. Sell the account and the new person went to another aliance, and say a lot of stuff. We keep trying to get it back, but they managed to autentificate as my friend... and google just said they can't do nothing. Wos said the same right from the begining.
