>the other is adding a username to a bot's watch-list
Which is exactly the same as adding a flag to a user's account.
This is some bizarre hair splitting going on here.
>That would be like saying that paying an employee to watch someone's account and manually delete every comments and submissions is a shadow ban. It is not. AutoModerator is an amazing piece of work but it is just that, a robot moderator
I don't know what you're trying to say here. What exactly, in your mind, is the difference between "a robot moderator", which is code that controls what is and isn't visible on a subreddit, and core reddit code, which is also just code that controls what is and isn't visible on reddit?
>The point is that "an unpaid, unaffiliated subreddit moderator" cannot blanked ban you from the website
Reddit is infamous for having multiple poweruser mods that are moderators over many of the most popular subreddits, and many of these subreddits share banlists (even ones outside the 'powermod cabal'). A ban from any one of these 'unpaid, unaffiliated subreddit moderator' will result in a shadowban from the majority of the website.
I hear you and agree that yes, a 'premium subscription' does not mean you're immune from bans, but you seem to also misunderstand the banning mechanisms on reddit. 'Shadowbanning' is much more widely used across reddit than I think you are aware of.
