Not really, the only thing close is a script off Greasyfork called Block YouTube Users. But it only blocks channels and doesn't signal YouTube not to recommend the channel (if you're logged in) unless you do it manually and then write the channel name in yourself. At least it's a sign that blocking extensions/scripts are still technically viable.

I blame it on Zuckerberg. Facebook was a disgrace for the human race.
