Business Insider has an interesting and in-depth article about the ongoing legal cases that could land eBay's two biggest affiliates in jail soon on charges of wire fraud.
If you've been in the online marketing industry for a while, you may recognize the names Shawn Hogan and Brian Dunning. They're the two affiliates that eBay and the FBI started pursuing in 2006 after suspecting that they were earning millions while violating eBay's affiliate terms of service.
According to court documents, Hogan made an astounding $28 million in affiliate commissions from eBay, and Dunning made $7 million. One way they did it, according to the FBI, was by using widgets that stuffed eBay tracking cookies in Web browsers.
If you go back and follow the links, you will see that it looks like ebaY made a *lot* of money on the deal then they turned around and double crossed these guys.
There was a *lot* more to it than that though. Beyond all doubt, one of the sleaziest, and most revealing episodes ever.
I think the same cookie stuffing thing or similar might still be going on today. Try it yourselves. Clean your cookies at the begginning of any browsing session. Do not go to ebaY. Before you close your browser, view cookies, checking for ebay cookies.
Why would (or should) ebay cookies be on your browser if you've never visited ebay?
