Discord gave selling hacks as the reason. There is no definition of what hacks, cheat, crack, or anything else encompases so you can't honestly say it doesn't full under that category. It doesn't matter if cheating in a video game is not breaking a low, criminal activity, or anything else. It isn't dystopian or protofacist. It is Discord policing their own platform with the rules they see fit to use.
It is no different then when MMO-Champion censors talk of certain topics like cheats, hacks, and etc. No one claims that MMO-Champion moderators are heralding a dystopian future or starting a incubating facism. If things like that ensures you'll never use Discord or Blizzard software again then why are you here as well?
