Worst age restriction I've seen was "If Star Wars Characters Were Charged For Their Crimes"

Depends what it's educational about.
Most subjects would be fine, but if it's that once science subject...

It's because age restricted videos are locked behind a paywall

MOUSAIT?? IS THAT YOU???

I'm not Mousait. but I do hate how that video I mentioned in the title got age-restricted.

It's Star Wars, it's like putting an age restriction on a Rated G movie which would be even worse.

YouTube censors that bullshit, but not literal p0rn
