Let viewers block a channel everywhere on YouTube

The submitted context

YouTube's existing Block channel control hides that channel's messages in live chat and comments and prevents mentions, while Don't recommend channel tunes recommendations only on certain pages. Neither creates a global exclusion that keeps the channel's videos out of search and every viewing surface. The cited community request explicitly asks for a channel to remain absent even during search. Please add an account-level block that removes a selected channel's videos, Shorts, live streams, and community posts from Home, search, recommendations, subscriptions suggestions, autoplay, and TV surfaces. Show a clear confirmation, provide a manageable blocked-channel list, sync it across signed-in devices, and allow straightforward reversal.
