I can't "be sure" because I don't have log-in info etc. but the above named person has way more than the average number of games that he has started where one or more of the players is a new? player, plays one or two games, then disappears. Current game I am in with him is 11502362 and in this one it's a 5 player game, he and I are both captains, then 3 players that have joined in the last day all of a sudden join within a few hours to complete the game lineup. He has one other historical game where the same thing happened and guess what...he won.
He also has NUMEROUS games where the LAST person in a game he has started is a brand new person.
I can't prove it...but I have no doubt what he is doing. I can't remember ever seeing one player with as many games with brand new people in it as this person.
This is BS.
