I'm interested in the ability to Block Worlds.

But additionally to that, I would like to just block all creations based on the uploader if I know a particular creator just uploads a lot of content I universally dislike.

This would allow me to block all of their worlds at once, and avatars, and other content, from appearing in searches or listings or being downloaded and loaded.

This is separate from blocking the creator themselves, as I'm sure they're a nice person.

There would be an exception for when my friend is in a world I blocked. Those should still appear with just a note that says "You've blocked this world." with the option to join anyway.

And yea, this is just another unobtrusive way for players to filter out AI content from people who frequently use it or people who spam it to upload "slop", but can also be useful for filtering out low quality or disturbing content.

This would also pretty much combine in this suggestion. "Allow hiding all avatars made by a specific user".
