What about affiliate links? with a internal transition page..i.e "please wait while we connect you"
We recently told G to nofollow these links because we spotted some in the index even through they were blocked in robots.txt.... the pages jumped from page 1 to page 3 on the next G crawl. Plus G now seems confused about which page to serve.
