On my subscription page, it shows shorts from my subscribed channels. On my main page, it’s girls in bikinis playing on a guitar, violin or drums. I wantch a lot of independent musicians doing instrumental covers, but I don’t recall seeing any of them wearing skimpy clothing.
I guess it’s sort of like facebook, to increase engagement. I stopped visiting there about a year ago, but I didn’t close my account. I now get one friend recommendation daily, and it’s always sexy looking girls I’ve never heard of. These sites register me as male, so they always combine my interests with sexy females, to entice me to spend more time there.
