Pills and drugs, again

A massive wave of referrer spam for all those fancy drugs and pills started over night and is still going on as I type this. This one provides yet another reason why it's a good idea to block those well-known open proxies at alestra.net.mx, since that's where most of the spam comes through:

148.244.150.57
148.244.150.58
207.248.240.118
207.248.240.119

He's also using another open proxy at 203.112.194.81, which belongs to BTTB, an ISP in Bangladesh.

The spamvertized URLs are from all sorts of redirecting services (move.to, esp.cc, etc.) and, AFAICS, all redirect to hqfinder.net, hosted at 66.246.178.76 (Net Access Corporation, NJ) and registered to

Of course, the names of all those pills also make nice filter criterions:
