I did not make the ban so technically I would not set the duration.
However, after the undertaking that you personally made to be in the last couple of weeks (21 February), I am of the opinion that you are not capable of following rules because they do not have any value to you.
I am fully aware that this is just a game, but that is a very dangerous attitude to have in life, especially for someone of your profession where compliance and the rule of law are critical.
I would not be expecting to see you back for quite a while.
