It's a good idea to contact Leon or Affixes, I'm sure it will be looked through if you're mature and ask for a second chance.
I think what you should've done at the beginning was Delete the Hyllus account and made another account named Hyllus which was a clean start for you when the idea of you post farming was going around.
But i wish you all the best and i do hope you'll be joining us.
Good luck on your studies too you were a very nice player
