"Legally, being signed in to YouTube means you are signing off that you are over 13. So an easy solution would be to put personalized ads ONLY on videos signed in users are watching. If someone is not logged in and watching, they should use CONTEXTUALIZED ads only...just like old fashioned TV. Base the ads on the content of the videos, not the data of the viewer. This would make the problem go away. It should be put into the YouTube contract that if you are a logged in user and you hand your device to your child, that should be legally considered parental consent. Also, WHY are they basically killing off kid-specific channels the way they are? The FTC is not making YouTube do that. It is absolutely unnecessary. Just use contextualized ads on those channels. End of story. "
Why is youtube killing all kids content? Why cannot they take parents' permission
