What should "block this YouTube creator" actually block?

ChannelFence launches tomorrow. I built it because YouTube's "Don't recommend channel" option isn't a persistent block, and the same creator can still appear elsewhere.

YouTube has more surfaces than I initially realized: Home, search, Watch Next, Shorts, playlists, comments, channel pages, membership shelves, and videos with multiple collaborating creators.

I've kept ChannelFence focused. You select a creator, and it hides that creator across supported surfaces. No keyword rules, accounts, tracking, or external server.

When you block a YouTube creator, where would you expect their content to disappear? Are there any areas that other blocking extensions tend to miss?
