I'd like to address the YouTube claim-- I find it really quickly leaps from my algorithm into a terrible place, from innocent clicks. One of the more common examples of this in my experience is: I want a video demonstrating the form for a specific lift. I watch it. My feed is immediately 80% weight lifting content, much of which overlaps straight into toxic material I would never engage with. I run into this issue constantly, to the point where I often avoid clicking on things I am genuinely interested because I am worried it is too adjacent to something else that is adjacent to something toxic. When I give in and watch it, I often enjoy it but find afterwards that I was right and my feed has a load of objectionable material on it.
