I cannot remove this individual, and, judging by his history, he's going to ruin my game.
First of all could you explain with a link or why you cannot remove him, there should be a game-creator who can remove any they want? By simply going to add/remove players before the match have started.
You could also just make a new game and delete the old one. Even if they have joined in you can still deleted the game as a whole and re-invite all players, if you have blocklisted the player at the point he cannot join(but just in case remove him before he can join, i thought the game creator already could remove players who had joined their game?).
