PPC scenario…
You bid and pay $1.00 for “casino” on PPC #1 (a legit ppc)
PPC #1 buys traffic for “casino” from PPC #2 (smaller but also legit)
Scraper sends traffic to PPC #2 SERP page for “casino” for affiliate earnings along with an 888 banner at the top and a 15 second redirct to the casino page.
Is that close?
