If you are watching youtube without an account then you are not posting comments. (The FTC article gives a specific example of a child posting a comment as being a disclosure of personal information.) Where is any tracking or collection of data whatsoever controlled by the channel host in cases of people viewing without an account?

If the child DOES post a comment, then that means they lied to YouTube about their age when signing up for an account. Why is this a channel host's legal responsibility, and what possible measures could be implemented to avoid it other than requiring an identity disclosing internet drivers license to be presented before each use of the internet.
