The way I read that, the scammer isn't in the Netherlands, dot tk is, the service that he went through to get a web address.
Dot TK:
Dot TK - Renaming The Internet Dot TK - Renaming The Internet
It looks like I can use the "copyright@dot.tk" to report copyright abuse, though.
I have tried every which way to google the scammer's website, and I can't get it to show up on a google search. I can find his ads, but the website itself doesn't seem to be "googleable". I don't see anything there for them to delist?
