I have seen this first hand.
Search an exact title they don’t like and you have to wade through pages of unrelated crap to find it.
20 years ago there used to be a photo of Jerry Nadler as a puddle in an alley. It used to appear frequently on FR. See if you can find it now. Imagine what kind of power it must take.
for some reason they keep highlighting videos that I have absolutely no interest in.......usually in days gone by, if you search for glenn miller, you’ll get lots of glenn miller plus lead on to similar artist..now, totally unrelated video promos are showing up....
I have had this experience as well. Or if you look up someone's name/channel, that they don't like, you will get the person's videos from 6 months to years ago, but only if you click on the person's channel, do you get their latest videos.
IOW it makes it look like someone hasn't posted anything in a long time.
Glad that Senator Cruz is trying to do something about this.
