I've carefully curated things to where my feed is actually pretty good and I've had little to no problems with it. Then out of nowhere I'm getting all these transphobic recommendations, especially detransitioner content. It was a wild departure from the usual and way beyond the amount of topic specific recs that I'll get if I look up something specific. It was really gross and I was already having a dysphoria day. Fuck YouTube.
You have to be really proactive with the "don't recommend channel" button, just off the thumbnails
That still let's the algo allow that topic though. Fortunately I went sicko mode and kept scrolling where I would see the same channel rec twice. First it's 'not interested' then 'don't rec this channel'. This is how I've curated a pretty nice feed for myself.
