Pot calling the kettle black much? If anything, what you've posted as your own art looks more AI. In one of your recent '3D models' you've got classic AI hands with too many or too few fingers and other telltale smudge-like irregularities.

Also, pretty sure the users aren't actually in the servers, the /ban command using a user ID works even if the user isn't on your server. I've used it to preemptively ban users once or twice when they're so radioactively toxic that I don't want them in the communities I run.

The ban command allows you to ban any user by ID, even preemptively. They need not be in your server, or have ever been in your server at any point for /ban to work.

That unfortunately only hides it. You can still use the apps, it just privately shows you the results if allow external apps it disabled, which is really messed up.

Unfortunately this doesn't really do anything. AFAIK all the stuff on the apps and commands is actually integrated into the client, meaning if a user opts in to use them, it probably does it directly through discord's API regardless of the bot user being banned in the server or not. It sucks ass.
