Any Google engeneer or executive can open an account at AdBrite, Linkworth, Yahoo and vice versa. That would not even be any illegal. So why shouldn't they all be doing that.
I am sure, Bill Gates has all sorts of accounts everywhere ... but just the wrong IT developers to get anything together. ;-))
Anyway, with this new "pls. report linksellers and buyers" ... Google will receive the "public note of excuse" for killing their links marketing competition by cutting sellers and buyers off from Google traffic.
... just to make search results better ...
perhaps that will even be, who knows.
