This is going to sound a bit weird.
And I may regret posting.
I watch Youtube both on a PC (for all kinds of purposeful things) and also, occasionally, on a set-top-box (for sports highlights where I don't have a subscription, video walking tours, animal videos, random light entertainment, etc). I never log in and never will.
On my PC, I filter everything fairy well - e.g. no ads. On the STB, I'm exposed to (what I think may be) the full onslaught of the Youtube algorithm.
A few times now, on the STB, I've noticed quite dubious videos being recommended. The relationship to something I've searched for or previously watched can be tenuous at best. Some videos, I would say, shouldn't be on Youtube at all. Some involve ... ahem ... apparent underage in borderline circumstances. It's happened several times; it's not a one-off. I can't report the videos (I looked into it) because that requires logging in. Most online discussions say reported videos don't get taken down anyway. (And, no, I don't watch online pr0n).
Frankly, some of those dubious videos look like 'jail bait'.
Has anyone else seen this? Is it the algorithm (in which case, what the heck are other people watching?!)? Or is it something else? If the Youtube algorithm (or some other mechanism) is actually 'baiting' people, I think it's useful to know.
