I block one number so they simply change the ID to a new number. Same as everyone. The call and leave a vague message about needing to call them immediately-never ever going to call them so, my blocked caller list simply grows each time.

A anonymous caller keeps calling 910 499 2684

Awesome!  Glad to see someone else is using them for entertainment. IRS, COMPUTER TECHS etc etc....the Mumbai [***] Clown Posse is an issue though. Hello my name is Sam Smith and you won't be able to understand much of what I'm saying. Lets see, your computer sent us the infamous virus SOS. So we need to remote access it so we can actually f..k it up and charge you 300 to fix it. By the way Im also an IRS Ninja and if you don't Western Union us 900 you'll be arrested. Ok sure thing and after you pound a bag of Mahatma Rice up your a.s sprinkled with a little curry call me back with the payment details.
