Harassing mesages

Some nut has been using my web site to send me insulting messages.  Like this: 

FULL NAME:
Harold C. Gordon

EMAIL:
haroldcg372llk@aol.com

PHONE:
212-555-7089

YOUR MESSAGE:
Old bald Bird Legs Harold. Nerdy faggot.

This person is using my name and I'm sure the email address he left is fake.  Can anything be done to stop this harassmenrt?
