The part about dropping "aff" (Which is all we really had to use) is great, don't get me wrong. I know that every word and letter counts in AdWords.
However, this "change" really doesn't do too much good, as, because as you pointed out, all it takes is a change to linking to a page that is nothing but the same thing the user would see if they went straight to the program site.
I could just change all my under top 1 links to point to a cgi feed of amazon at
http://www.publicdock.com/feed.cgi for example. Or more of a specialized site, for example
http://www.benemptor.com . It doesn't really help the consumer, merely further cloaks the real source of the good being sold.
I have seen a drop in clicks the past 4 days (As I'm changing over to new type/formats of linked pages), but my conversion ratio is slightly up, but I attribute that partly to our getting further away from Xmas.
Anyhow, I'm not sold on it, and think it just makes more room (Incentive?) for abuse.
