This site allows you to sort your favorite YouTube channels by their dislikes. I’m not sure why you’d want to do that but checking out some of my favorite channels it was interesting to see what bubbled up to the top from sorting that way.
It was also interesting to take a look at the Most Hated channels (caveat – It’s YouTube I have no way of vetting all those channels to make sure the content is appropriate for all viewers. Maybe don’t let your kids do this) which shows the channels with the most dislikes.
I thought, overall, this was an interesting way to engage with content you might not otherwise see from your favorite channels. Give it a try for yourself.
