Even if that was the case, i don't see how having an external program like FanControl, Nvidia Profile Inspector, a BIOS setting that may be turned off/on (speculatively) grants for a "Permanent penalty" if the anti-cheat randomly flags it out of nowhere and there is no one with access to the log files as you said that could collaborate players and tell them "briefly" what went wrong.
A reasonable solution would be to not let them into the game with a warning and a suggestion of what the cause could be, as other titles do until resolved/system is polished, instead of wiping their entire account over a false flag.
As for people being unbanned, i am aware of 2 people personally, both Japanese, both content creators which is a needle in a haystack among the tons of falsely banned accounts of regular people, some claim they haven't even played the game in months and log into a banned account.
And of course we persist with multiple appeals, i don't just believe in my case, i am 100% certain. If i was a cheater of any kind i wouldn't write essays on here, i wouldn't waste time to read about people being banned on Twitter and Reddit, speculations of causation nor try to get myself unbanned if i had any suspicion it could be on my end.
I rule out peripheral softwares because they're web based on my gear so there shouldn't be any suspicious 3rd party files clogging the Anti-cheat.
A common theory among the japanese players seems to be USB related, unplugging/plugging a device which sounds absurd but at the same time, as a mouse and keyboard player i often have to plug my wireless mouse mid match to charge.
I understand that the ToS team cannot and will not fully disclose everything but at the same time having some brief exchange with what it feels like "a real human being" instead of the exact same automated email would be great for the players.
e.g. "Hey your TPM 2.0 is disabled, please turn it on" or whatever. Just as an example, i don't know if they can or cannot detect what Windows version you're on and what settings are enabled/disabled.
I know there are some reasonable flaws in this logic as you've explained why that wouldnt work, it'd help cheaters to find loopholes etc but at the same time is sucks so much for the end-user to have no clue what triggered an issue in the first place nor how to resolve it especially right now as it is not an isolated case and the ToS team is likely flooded with countless cases they have to deal with. I even considered giving Live Support a shot but when i saw automated chatbot with generic questions i gave up as it was yet another dead-end road.
