Take the story of 10-year-old Alex. The precocious techie had a Gmail account since September 2009. But when he signed up for Google Plus last week and entered his age, he was kicked off not just Google Plus, but Gmail as well, for violating Google’s terms of service requiring its users be over 13. All of his emails to grandma are going to be deleted, and his dad wrote an impassioned blog post accusing Google of making his son cry. Now the memory of young Alex’s first BCC is lost forever.
