It's a similar problem to people being banned from Google (insert big company name) because of an automated fraud detection system that doesn't give any reason behind the ban.
I also thing that there should be laws requiring a clear explanation whenever that happens.
That doesn’t seem like a good comparison: it’s a far more serious crime, and while the bank won’t tell that they’re reporting your activity to the authorities the legal process absolutely will and in sensible countries you’re required to be given the opportunity to challenge the evidence.
The problem being discussed here feels like it should be similar in that last regard: any time an automated system is making a serious decision they should be required to have an explanation and review process. If they don’t have sufficient evidence to back up the claim, they need to collect that evidence before making further accusations.
while it is infuriating, it's common for every place where fraud is an issue. if the company gave feedback, it would open the door to probing and know what is being watched or not. same reason as why a bank will not tell you why you got kicked off.
