I don't know if Marc will have some time to look into it...
All I could find are some failed logins. Though not very many.
One possibility is that they hoped someone would post the entire email (incl link) here, and they could see it and use the link. (after all its a password recovery, if you have that link you don't need the password).
Or they didn't know the emails of the users, but they had accessed to hacked email accounts and were randomly trying if any of those mails would go to such a hacked email...
As long as the email ended up with you, and no one else, then its just an annoyance.
