After doing a bit of research on this, I get the impression the link on the gallery was in fact switched. if you take a look at this alexa cached version, you'll see:
Actual URL:
http://onlyteenfiles.com/tf/abril/01
Cached URL:
http://64.213.200.107/cgi-bin/docach...S3NDa xNDIHAA
If you look at the links to the sponsors from these two links, you'll see the second link goes to:
http://www.topadult10.com/search.php?aid=71655&q=Teens
The actual page (now) goes to:
http://www.teenstarsmagazine.com/proc/?
My guess is that this content was probably ripped from TeenStarsMagazine and was being linked to the PPC search engine. Whoever ripped the site used the stolen CC, made his quick cash with the PPC search engine and when it became apparent the CC was stolen he switched it out to the actual paysite he ripped it from. This is likely why the affiliate program owner had no spike in traffic or sales, the traffic in reality went to the PPC search engine.
I think you should be contacting whoever owns topadult10.com and pass on that affiliate ID and trace who owns that account, that's likely the culprit. It seems that TeenStarsMagazine isn't actually the one who did this.
Hope this helps...
