Why does TikTok show a black thumbnail on people’s videos?

I noticed some videos have a black thumbnail as opposed to showing a still image from the video. I noticed this particularly with accounts of people that appear to be under 18. Why does TikTok do this?

Probably for the same reason you're scrolling the profiles of people under 18
