While not entirely on topic, I am implying that the person who is getting the unremitting password reset requests may have an e-mail address with a similar problem.

My <common-name>@<common-name>.com address gets incessant password reset requests for every major online site in existence. (I should have been clearer about this; sorry.)

I am suggesting that, by having strange or very unique e-mail address, you can fairly effectively mitigate this phenomenon.
