Since the Charlottesville incident, when AirBnB permanently banned an unspecified list of people they identified as Nazis, I've always taken a closer look at ToS and AUP for various cloud services, many of which claim they will permanently and immediately ban you for transmitting or storing things that are "offensive", with no further explanation given.
Bans like this are yet another transparent exercise of platforms' power. Where does it stop? Amazon clearly has the technological ability to ban you from Whole Foods if you returned too many items on their website or wrote some bad things about them online; I'm just waiting for the first Medium post about it. Can the phone company ban your number if they don't like who you're talking to? Hell, even my apartment lease lets them terminate it if I "engage in criminal activity", not requiring "criminal charges, arrest, or conviction", but by a "preponderance of the evidence in our judgment".
