I think trying to argue that the viral/algorithmic addictive short-video feeds are "social media" is a bit of a stretch.

If you banned any network that does algorithmic feeds, or that don't have good moderation, then I'd be fine with my teenagers using it. I think the problem is the mind-numbing video scrolling more than any other risk with social media.

And I don't think there's a danger to it per se, I think it's just too addictive and distracting.
