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?

Recorded really early 20th century movies or acts.

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.

Honestly if they can verify that i'm an adult based on what i watch and stop blocking videos because they might not be appropriate for a kid like mf i ain't no kid.

Listen to some classical music

IT certification training videos.

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.

lol, many adults will get flagged as kids:

you keep clicking on YT Shots
watching Joe Rogan again? sus

Ben Shapiro fans in shambles

And give up on making you explicitly hand over your identity... Sir/Ma'am/Other I believe you have misjudged the ever beneficent Google. This will simply be to augment the other fingerprinting methods they already use regardless of what they might say.

Was gonna say.. my kids keep accidentally using my profile to watch their videos. YouTube is going to think I'm a teen/child with peak gen alpha brain rot.

Will start?

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

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

Hopefully my frequent playing of 90s music playlists works out!

Is that the green iPad man?

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).

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

You do realize that there are a ton of adult fans for kids shows and games right? How quickly the bronies are forgotten with everything happening in the world.

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