The bad guys are real, especially on the Internet. In fact, the bad guys of the Internet are worse than those in real life. At least you can SEE the ones in real life and defend yourself or flee. The baddies of the Internet come into your house, sit on all the furniture, make a mess, and steal your stuff….all while you are in the kitchen hanging out unaware!
No amount of security will stop them from attempting to break in and nothing is foolproof.
