Full of cheaters
Its so lame of 9M to allow players to cheat using vpn or other connection apps controlling in/outband. In a real 1:1 online, one user should not be affecyed by others bad connection or cheating with connection. Plus, the court speeds are not equal within the same court type, in the same day you get normal/slow/speedy speeds, which allow cheaters to win even more, there are cheaters winning 200+ games in a row, are you kidding?
