Best I can come up with: people flag shit and it goes to a server, and like PiHole, anyone subscribed to that server will have the crap excised.

I'm liking Apple's "Hide Distracting Items…" feature in Safari. Now if only everyone's audits could be shared, a consensus arrived at, then others could be spared having to spend time hiding-distracting-items themselves.

A kind of HTML shadow banning?
