I got a call from these guys yesterday(07/01/09). Now they're calling themselves OTA Express. I think they're trolling jobsites looking for victims. The website they're using (OTAexpress.com) was set up last month by a guy named Swoope in California (probably an alias. DON'T VISIT THE SITE: It's booby-trapped with malware.
Another phone # associated with these guys is 601-767-2793. I notified netfirms.com, the hosting service for OTAexpress.com, of their suspected criminal activity and they shut them down. Kudos to Netfirms for their swift response.
