@mattly oh oh the other one, this is a more complex sequence
1. try to log in from a link in a legit email
2. fail. tell it to send you password reset email
3. "invalid email address" / "no such email address in our records"
4. "too many log attempts you are locked out"
5. 🤔 lock out the "unknown" email address, hm?
I am perma-stuck in that situation with a couple online accounts. one is a bank, and I had a VC meeting with the bank rep, and it still could not be fixed.
