1) The tournament is amateur, and therefore there wouldn't be any major consequences anyway; the winner of the tournament doesn't gain anything besides positive emotions (the rating appeared later).
2) He is still a novice, and although the violation was intentional, it can be understood.
I believe that giving him a second chance wouldn't be a crime. In any case, people will still treat him with caution. This will be enough for him for the first time.
2 Shadowman, keep playing, but do it honestly; you'll gain experience, learn the nuances, and playing will become interesting for you without using codes.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
