How the fuck is it possible to airdrop files to strangers' phones?
That's a massive invasion of privacy. Just imagine getting a notification on your phone while you sit on the bus, and when you click on it, it's a pic of the guy sitting in front of you jerking his cock.
Fun fact: The Chinese government can routinely overcome the encryption used by AirDrop, which allows them to track users and get their phone numbers and email addresses.
