official complaint for accusing cheating

Hello, quick story.
My 15 years old son started playing chess at the beginning of the year. He learns extremely fast and in a couple of weeks start beating me easily. I encourage him to start playing on line and last week he starts playing in the tournament.
Yesterday his account has been closed because of cheating, but nowhere has been specifying what he exactly did. I know for sure my son did not cheat and whoever accusing him of that has to be a brain deficiency person.
He appeal, but only what he received is to open a new account.
Accusation without a prove it is a serious crime, maybe when you have to pay compensation, you starts thinking, because for now it doesn’t look like.
I thought to buy premium account for him, but you just proved it is not worth it.

By the way, I will share my son’s story on any social media platform, as a prove you are not respect players and you accusing people for not fair play game without presenting any proves.

This happend to me a few days ago. I won 20+ games( i guess only3 loses) in a 1 minute bullet tournament. In 1 minute you cant think like its a 10 minute game so you have to react fast. The problem was that my opponents were all 100-1000 elo. And iam/was 1700. Idk why i got banned bcs i also had many blunders and i didnt even won the tournament. So ig this happens often :/

This is unfair to 15 years old boy who is passionate about chess and accusing him of heating it breaks his heart. How to explain this to him? I know he did not cheat at any point.
If this happens often it means the rules are stupid and people who apply them are more stupid than the rules.

The site won't release details about detection methods or exactly what was triggered. However, it doesn't close accounts unless very certain. You stated there was an appeal made and in that case staff take a deeper look to make sure there wasn't a false positive in the process, leaving the only option to create a a second chance account.

The site closed over 121,000 accounts in April, including 13 titled accounts. They are very confident in the detection methods and upholding closures based on them.

That said, discussions of cheating, potential cheating, or cheat detection are not allowed in the general forums.
