I'm surprised at how many people in this thread are focusing on the "Google locked the account" as the bad part of this. The clear fuck-up on Google's part is rather that they didn't provide any avenue for Alex's parents to accept the contract on his behalf. Nobody would be complaining (other than the usual light grumbling) if the lockout message had been something like this: "Parent permission required! Our records show that you are not yet 13, so we have blocked access to your account. To restore access: If you are at least 13, click here to send proof of that. If you are under 13, have a parent or guardian click here to link your account to theirs and accept the terms of service on your behalf."
