Getting spams from Opinion Surveys?

I've been receiving spams the last day or so from an outfit called "Opinion Surveys". In the true tradition of spammers who send penis enlargement adverts to women, they send me an offer to join a sweepstake which is only open to US residents, and claimed that I'm a member of theirs, which is news to me. I've got a Unix box (a Mac!) which allows me to do a traceroute on this spammer's host. Here's the headers:

So, if you've got this spam, the address to complain to is abuse@gblx.net, which I managed to get off Global Crossing's website. Don't hesitate to complain to them!
