It wouldn't seem that difficult for nerds to game this. Randomized searches on Amazon and Google run occasionally in the background, while all real traffic passes through an encrypted VPN (the speed hit theoretically being negligible over fiber). Still, most users will probably just shrug and accept it as normal, much like with Kindle "offers". Not exactly a positive trend-line.
