Most likely some “friend” or relative filled out one of those cards and sent it into the bank. From there, it’s all automated.
My guess too. This the type of thing a hacked-off ex might do.

One day we found his address and sent in a couple of subscription cards in his name for some totally filthy sick perv magazines (they made Hustler look like Boys Life) BUT... for a little twist, we put a couple of his neighbors' addresses on the cards. ;-)
Yeah, I'm thinking in this case, this slut girl ticked somebody off.
