Ban appeal

Quick question, how can we appeal a ban? I left the game over a year ago, never had any issues. Trying to come back and my account is banned, no idea why. Followed instructions and DMed @CG_LucifersDaddy last weekend, but never got an answer. Is that still the way to go? Read somewhere he might not be active anymore.

Appreciate any help I can get, I really want to start playing again and don't want to start over (had all 6 GLs at the time and unlocked malgus and such).
