So looking over some information, you came back around the 21st and you've played a fair amount of rounds since. However, given that this was the highest punishment that could be applied barring an actual server ban, there will be a measure of scrutiny.
Personally to me, the two years hiatus does not really factor into this as something relevant. I look for improvement of play, which requires time on server. Being around from the 21st to 26th is not enough to me especially when you factor in player history.
As written previously, a hiatus of two years does not give me any indication of improve or change.
Appeal denied.
