And YouTube isn't really interested to improve their suggestions: when I say "Not interested" to a suggestion, they ask why not with two idiotic possible answers: a) I've already seen it or b) I don't like it.

If a) would be the case, they most of the time would know it and if b) would be the case, I would have seen it too and thus a).

Examples: I use Canon and Fuji gear for taking pictures, but they offer me Nikon or Sony related videos. If they would actually have some interest to optimize suggestions, they would offer me to say "I'm not interested in Nikon/Sony/whatever" … wouldn't they?

Or Amazon, offering me Sony lenses for my Fuji. Or more of Thing-X after buying some Thing-X yesterday. But I only need exactly one new Thing-X, which their stupid "AI" Rufus should know by now if their suggestion machinery didn't know it already ;-0

I’ve stopped using “not interested” because it’s so shitty and pointless. It has no effect whatsoever on the other videos YT decides to show me. I swear when I clicked “I’ve already watched this video” the Home Screen would show more previously-watched videos than before.

I aggressively nuke channels instead, and use a ublock script to hide anything with a red bar (which means I previously watched it).

I find it very effective.
