Same email used for amazon as you use for your YT? They may be linking you by email and knowing if you view his videos and such.
They even know if you follow him on twatter etc
I can't say I am a fan of Corsi , I do not like how he twists the intel and has stated things such as "Loop Capital" not being important.
But I do however think its pure bullshit for that to be happening. He has written many best seller books for over 25 yrs. Who the hell does Amazon think they are ? Part of the NWO thats who. .
