As to the bush plane videos, have you watched Trent Palmer? https://www.youtube.com/user/boredentertainment88/videos
Yes. I wish he would stop wearing baseball caps with ghetto flat brims, even
in the house. It makes me want to reach through the screen, rip it off his head, and punch him out.
I did clear cookies a week or so ago, but that's not the cause. I've done that before, and it usually takes one day for them to pick up on what I've been viewing and start suggesting videos in line with what I watched the night before. This has been going on for over a week ... within which I haven't cleared cookies.
Yeah, looks like they're changing from offering what you like, to pushing what they like.
That fits what I'm seeing. One has to wonder why anyone thinks pissing off your viewer base is a good idea.
