Of course, if a player who has received a ban is again the subject of investigation, and the investigation concludes that the player has cheated again, then there can be no question of lifting the ban after a certain period, and the time period will start again.
In Vitalik's case, however, there have been no further violations, and therefore lifting the ban is possible.
A general period of 1 year can be set, but under certain conditions, the possibility of an earlier lifting of the ban should be considered.
