Glenn - you can go after the guy...
His name and address is available from the whois:
Lavery, Joe
[email protected]
448 Dixon Road
Queensbury, New York 12804
United States
8666471646
His host is Hostgator.com - he has a reseller hosting a/c with them - so chances are he has more than one fraud website. So getting him down is a good idea.
He registers his domain with wildwestdomains.com - which seems like a godaddy.com reselling unit. So you can complain to godaddy too.
Also - you should contact clickbank.com - his clickbank id is mhminc. And get that closed.
And you can complain to aweber.com too - which he uses. His aweber id is mhcprospect. And you can see the email he sent out with your product here:
