That name you gave https://www.chess.com/member/jad3n1nja has not been banned. He only played 2 games, the last in 2018. Maybe his username is slightly different .
Even if he had been banned, I can guarantee that he wouldn't have been banned for using a scholar's mate.
Usually people are banned for fair play violations.
Some players are banned for abusive behavior.
He should have received an email explaining his options. Ask him to show you the email.
I found https://www.chess.com/member/jad3n1nja2 had been banned in 2023.
If you look at the history, it is obvious why the account was banned. The last game does have a scholar's mate but that's not why he was banned.
If that is his account, he should contact Support using the Support link and ask for a second chance.
Thank you, yes, it was that banned account. Sorry, it's never been obvious to us why he was banned. I don't play many people online and he doesn't understand everything about what he's doing. We'll go through the support channel, but before you remove this, could you please give us a clue to what he did wrong?
I am not allowed but if you look at the account game archive, it should be pretty obvious.
Thank you, please delete.
