What kind of script this two trashy sites using?

I really interested in purchasing any script similar to this site shexy.nl and getacd.org . Those two sites are GARBAGE, but they attract so many visitors. Getacd.org's trafict has skyrocket in the past 2 weeks. I've been checkin them in the last couple weeks. Everytime i search something, I always ended up in those two sites, and they have no information i was looking for whatsoever.
WHat they did was.. i think they harvest all keywords from the visitors. what kind of script are they using? Any script or website similar to shexy.nl and getacd.org for sale? thanks

Its the same kind of method all those pirating sites use so that when you search for an exact version of software they have a megaupload version and a rapidshare version... its basically a way of mass producing spam.

If I were to make that, I'd just store all user searches and make a file with that keyword in the template, the header, in bold, etc. Once you get to a certain point it'll increase exponentially - just make sure all the pages link to something and are linked to.

Other than that, I'm not going to give a guide out on how to make useless spam
