Honestly, this looks more like an improperly referenced student project than a real content spamming site. Parasitic scrapers usually get their revenue from ads. Notice that there are none on any of the pages. Maybe I'm just naive.
EDIT: My search through DNS registrar supports that theory. Spammers can easily hide their contact info from public listing by paying some extra bucks to domain name provider. This one is wide open, including registrants email and other contact info. Yup, this definitely seems to be an amateur.
My suggestion is to simply send an email to this guy, explaining that whatever is the reason why he made the site, he has to include the backreferences and other stuff that license requires. I still may be naive, but you can catch more flies with honey than with vinegar (not that I ever tried to catch flies).
