Google's growth rates are starting to plateau, and they might want to revisit the legion of people they've robobanned from spending on their platforms.
Fraud occurred here. Google just shuffling the shells might be aiding and abetting fraud.
(The law here isn't set up just to protect Google; nor is it set up to just protect the kid. It ties into broader societal protections against child exploitation and child labor. So Google runs the risk of tripping over criminal liability, in which case the end result is no longer in the hands of any of the immediate parties. Their policies are maximally paranoid to avoid that outcome).
Utter nonsense.
"Hold on, you are 13? Get your parents to call us, they'll have to set up that account for you"
b) Worries about child labor: already happened. Google profited from his activity already. It's just the kid not receiving anything.
