Write to gmail.com administrator and make it stop. I had a DUmmie sending harrassing e-mails until I threatened AOL with the FCC and it ended immediately. The added bonus was in knowing that somewhere a DUmmie found itself defanged and neutered.
If it's bothering you, you should remove your contact info from your profile.
There is a guy offering gmail accounts (in his tagline I think) whom I've seen posting recently...has admitted to being a lefty.
