Near Undetectable Cookie Stuffing?

A while back, I noticed a website for sale on Flippa that was getting some good traffic. And, how did the owner monetize that traffic? Cookie stuffing!

The problem with directly cookie stuffing your own site traffic is that a growing number of networks are using bots and manual reviews to detect and ban cookie stuffers. Even if you are CSing based on referrers, excluding known networks/AMs IPs, using random throttling, etc, there is an ever greater risk of being caught.

One ‘smart cookie’, a member of WPBlackhat, came up with the idea of using a modified version of CPA-R to cookie stuff while faking the referrer. Let me explain it more…

Let’s say Blog A is your high traffic site. You create another blog called Blog B. You submit Blog B to the networks – the ads/banners go on Blog B. When visitors go to Blog A, they are cookie stuffed but the referrer is spoofed to Blog B. Blog B NEVER cookie stuffs any visitors. Bots going to and manual reviews of Blog B will never find anything suspicious. Here’s a simple diagram to illustrate it.

This new CS system will comprise of two WP plugins and will be released in WPBlackhat in the next two weeks after extensive testing. Although, with the above info, CPA-R which can be downloaded from this blog, and some knowledge of php and WP plugin creation, you could create your own.
