Sounds like your algorithm is pretty badly poisoned.

It's my primary video entertainment service. I have a premium family plan so I don't have to deal with ads on any device and neither do my wife kids or parents.

I don't see any crypto scams. I do occasionally see clickbait BS in the suggestions, but I've gotten pretty good at avoiding it. Even creators who put out things I like, I'll delay watching stuff with clickbait thumbs or titles so as not to reward it. I found the Veritasium video on clickbait informative. (Funnily enough he's now on my shit list for clickbait)

An inexhaustive list of my follows off the top of my head:
Gaming:
Many a true nerd, mainly for the fallout stuff but I like their other content.
T90official, for AoE2 match coverage, the nearest I get to watching sports
Best Guest (he deserves more subs, with his surreal challenge runs) SorcererDave.
Karl Jobst

Science:
PBS space time.
Anton Petrov.
Sabine Hossenfelder.

Legal commentary:
Leonard french.
Steve Lehto.

Tech:
Linus Tech tips (although they're all in on the clickbait titles & soyface)
Gamers Nexus
Der8auer EN
Louis Rossman (I've become less of a fan over the last few years, but not enough to drop him)

Other
Meatcanyon/papa meat
Rainman rays repairs (the algorithm offered him up, and I've found him fixing stuff pretty compelling lately)

There are more but that all I want to type out right now. Some also broadcast on Twitch, but I'm not a fan of that platform. I like some editing, and can't stand the "look at me, look at meeeee" aspect of twitch chat (or any 'live' content)
