"or if it was received at any time after their first participation in a Valve-sponsored event (e.g., after participating in a qualifier for an RMR event). "
the ban was received at 14yo, on my logic that would free him. He didn't take part in qualifiers while being pro, did he ?
EDIT: he took part in 2 open qualis for the europe minor for katowice in 2019 and placed 9-16th in both. If he stays banned for that I don't even know holy shit
