I now use the right click "open in new tab" on any video so if it is AI, I can close the tab then hit the list where the video was and then go to the action dots to the right of it and "do not recommend" the channel. Have managed to give most of the godawful HFY videos the slip (..though recently new AI channels have popped up in my feed.. Urgh..)

Same, but I don't think it will. Luckily YT is demonetizing AI slop channels, so people running those at least have to do more legwork now in order to make it worth it. Overall, it's good that all indicators suggest YT is recognizing AI slop as a problem for their platform.

I made a video about training your personal version of the algo to suggest less of it, in fact, but since you can't outright turn it off, there's no magic bullet.
