No, that's not what this mod is for. The closest I can think of would be
Mail Admin When fail to login to admincp V2. It will trigger when they reach an admin account anyway. Maybe.
I can't imagine a spammer taking the time to do this. I mean, we're not talking breaking a single account by brute force with unlimited password guesses. Rather, they would have to move from account to account before starting over with the first one with their next guess. And if they got back to the first account too soon, they would get locked out.
