This is most likely an automated trigger that blocked & scheduled for deletion that account. Even for a company as big as Google it's impossible to have these type of things reviewed by humans. What I do hope is that they'll create a channel for complaints if the user should want to.
What I don't understand is the way the parent behaves. He knows he's in the wrong and he still feels outraged because Google blocked the e-mail. Even though nobody reads the ToS it doesn't mean that they are moot. Google didn't make his son cry, his father did.
