I'm a newbie, I have a question for the headquaters.

My last accuont, LeMinhKhoi is banned because I used AI for coding in a contest. I knew it was unfair to use AI, but what if an unrated account got to the top of the leaderboard, undercovering as a noob, like doing a challenge or try to rebuild an account, what will happen? (I'm a newbie, please don't judge)
