no, I mean remove the ban. Or is it only for one day then I can play normally?
You can't remove ban.
You can only wait the ban lift.
The ban have many different freeze time depending on how many rules you cross when play the game.
I heard in AK,
first got 1 day ban as warning,
7 days if you ignore first the warning,
1 month if you doing it again after second ban,
And 1 year+ if you doing it again without care about the warning.
But if you doing something too extreme at before first warning (like op inject or something who have big danger) you can get last punishment at first warning.
