maybe this has already been mentioned but I was reading about some upcoming changes at EPN....i pasted below what i read
"I was fortune enough to catch wind of a new filtering process that EPN will begin to implement full scale in April 2010. It's called Click Forensics Technology or CFT for short. EPN has signed a contract with Clickforensics.com to filter it's traffic for click fraud, trademark and quality.
One of the things that CFT will do is measure "User Intention" for lack of a better term. The way it was explained was that let's say you did everything right, built a really killer blog that ranked in the top for "Diamond Shaped Blue Widgets". I'm talking by the book, 100% legit site. No BS at all.
Obviously Ebay will have these "Diamond Shaped Blue Widgets" listed in auction or BIN format. Through "patented technology" Click Forensics Technology, Inc. claims to be able to determine and filter clicks that would have found these items on Ebay regardless if they visited through your site or not. Your QPC will adjusted to reflect this.
Beta testing has already begun.
This is only a small portion of what CFT,inc claims to be able to do. Interstingly enough, two of the founders of CFT are former Google Engineers.
I am in no way suggesting people drop EPN or whatever.
Just giving you some heads up and this was the last straw for me."
here is link to the company announcement

That's a bunch of horseshit, get ready to bend over.
