I have started to click "don't recommend this channel" quite a bit on YouTube shorts and I am finding it is recommending me more channels like the one that I just said I would never like to see again...
"Don't recommend this channel" flat out stopped working for me a couple weeks ago but I used to use it all the time.
The best part is, every so often they show up with "want to watch something different?" which seems to be a list of everything I explicitly said I don't want to watch.
To be fair, that has a twisted logic to it. Videos you have no interest in watching definitely qualify as "something different" compared to ones you do watch.
My favourite is when you did click don't recommend channel it sometimes still comes back after a year or two like a bad relationship on Facebook. I try and maintain a few browsers with different recommendations streams and it's always wild when I have a new PC and I get some really toxic recommendations.
