i received that mail few days after i rented a movie and downloaded it. (mail on August 1st - rent/dl on July 29). / I returned the movie after the dl 2 safe the money ;) .....
since then, i have downloaded stuff from a few amazon channels, and i didnt receive a new mail / a ban.
So i m pretty sure, this is only about renting/buying movies - downloading - then returning it.
