If you've already won or lost the game, then yes, exiting the window is completely fine and won't put you on a fair play restriction or anything like that. If you exit the window and the game still is active, then you may be placed on a fair play restriction.
The only things that affect your fair play restriction are disconnections, stalling, or aborting games.
Hope that helps!
Can someone help me out with how we are supposed to exit the game right after playing? because if i remember correctly, after the win or loss, you exit the tab of who you were playing with, since there is no game in progress, but not aborting or anything, they have been restricting me of playing for not following their policty when im exiting a match the same way i always have been. where do i reach the people from the site to dsicuss my situation?
