Companies can give the exact reason for a ban at least, without disclosing the methods of deduction. There is absolutely no reason to hide this information.

Such a behavior of companies is a big "f*ck you" to democracy and justice, not to criminals. It's exactly how totalitarianism looks like.

Ofcourse it does, a corporation is a totalitarian organisation by design - I don't understand why anyone is surprised to learn this. Any disobedience or herecy and you are removed with prejudice.

The exact reason is probably that their ML model told them to. They probably have no ability to give a more satisfying answer.

I don't think their model just says them "fraud/no fraud". There are different types of fraud, which should be written in their TOS.

No, this is not how these systems work. You're correct that they don't say "fraud/no fraud" but they generate a score (like a credit score) based on a massive number of inputs, and there are thresholds over which action (account ban, etc.) is taken. It does not in any way map to "types of fraud" and it does not map to the TOS. It's about identifying activity or accounts that look sufficiently similar to previous bad actors.
