Why are our Salesforce accounts getting blocked for high-risk proxies?

Legitimate network connections are being incorrectly flagged as high-risk anonymizing proxies like TOR or Mullvad, causing administrator accounts to be repeatedly blocked. This leaves organizations locked out of their accounts for months without a clear way to prevent the behavior.

“The owner of the company at one of our MSP customers just had something unexplainable happen. This may shock you but Microsoft is involved. She forgot her email pass to log into a brand new mobile device. I went to change her password and it threw the error "This user's password can't be reset because password writeback isn't turned on for your organization."”source ↗
