I think it started about a month ago, but recently got out of control. I mark ALL videos on my homepage as not interested, refresh the page and see about 20% of videos I just marked suggested again. Or next day, or the day after.
It seems Youtube just decided to ignore my "NOOO" signal.
Anything I can do? Any tampermonkey scripts that will add the video to local blacklist database and hides it from suggestions?
