I got an FBI warning after clicking on a advertised porn site( I know it is a bad habit and I've been trying to break it) and a popup said 100 dollar fine and then it said either locations or ways to pay and I hit the home-button and it all went away. It did not lock my iPod and I have gotten no other warnings. Was this real or a scam? I am really quite scared about all of this since it doesn't look like other fbi scams. Help!
