Well.. if you're using it on your computer, there's extensions to block channels and videos, so they never appear.
But still, when you're logged in you can click on the 3 dots on the video, and click on "not reccommend channel" or something like that.
That should do the trick.

Thought the same ^^

The thing I hate on YouTube is how whenever I watch a YouTuber I like, the comments are always like,
“This comment of mine won’t be pinned” or “if he pins this comment I’ll delete my YouTube channel” or “Clicked faster than I typed this whole comment”. I don’t blame you wanting to stop using it, especially when YouTubers I used to like, like Penguinz0 started using Brainrot language and others also,
I’m talking too much I’ll end it here XD

Honest to god, YouTube is fucking hell. Like all the brainrot shit is fucking abysmal and ppl are so fucking negative, like they're kids dying in Gaza rn and yet you wanna complain about Mario Kart or some shit like that? Grow up! And they also pay stupid ppl to do stupid shit, thats the reason Logan Paul filmed that dead body in Japan. YouTube and social media in general basiclly allows terrible people to be terrible yet punish ppl who use the site normally. Also they want your GOVERNMENT ID so you can access certain content. Like how are ppl not outraged, this is some North Korean type shit. I could go on about how YouTube is litterlly the devil, but I'd be here all day XP

You can put "Don't suggest this" on such videos to help ^^

You might want to look into this if you are planning to leave YouTube for good.

’YouTube’ alternatives

I can handle your opinion on this site (Like & Originated from it), as I browse carefully on what I love to watch from cohesive story & well designed character videos from goanimate, to On-Ride POVs to parks I'd love to visit someday.

At least this kind of hatred is better than how DonaldDuckandGoofyYes MickeyMouseandMinnieMouseNo poetrays it as they claimed YouTube as a Person when it isn't.

YT is not fun anymore
