I think you got it backwards. What are some categories an adult would never watch? Fucking Dora the Explorer and Blues Clues and the like. Although it's very likely they just play it from their account for their kids.

Vanlife videos, cooking shows, and politics should make YouTube believe you're an adult. But hell I subscribe to gaming channels, with watching gamers play games. Will that get me labeled a child.

So, if you're a child, watch some videos about budgeting, maybe a few cooking videos?

I dunno, what are some categories of video no youth would ever watch?

It's interesting that you mention the gaming thing, I've realised recently that I'm still watching the same folks I was 10 years ago, so it's really content by millennials for millennials - not a child thing like I'm used to assuming. It does come in part because if I mention YouTube to a younger person I get a blank look when I say who I watch.

Recorded really early 20th century movies or acts.

Is that the green iPad man?

Will start?

I'm pretty certain that they're already guessing as much about you as possible for targeted ads.

Good fuckin luck, I'm still getting Spanish ads for womans deodorant. If they can't figure out my sex and language age might be a bit rough for em

Your last sentence scuttled the point of your first two sentences.

So watching a Australian man review mp3 players will mean what?

My viewing history can legally drink in US in a year. What do you mean „guess”?

There are problems with this. Firstly, people might let their kids watch videos on their "adult" accounts. YouTube's detection would have to be incredibly fine-grained and be able to flip-flop depending on what's being watched.

The second one is a "damned either way" kind of deal: Consider the deletion of watch history; Should it forget you're an adult if you do that? If yes, then you have to go through a different process or watch a load of videos that are not blocked but still sufficiently adult to get your account reidentified. If not, they're storing metadata that you implicitly requested the deletion of.

I have reason to believe that they do keep such metadata and that they may have been taking steps to hide that fact. A permanent "user is an adult" flag would blow that wide open. As such, I reckon this will be the first, "forget" option. And users will have to suck it until the algorithm works out the user is an adult again (or else never delete their watch history; something that would suit YouTube's advertising algorithm just fine).

I play a game from 1999, I guess I'm safe
