Phone scammer identity theft
A friend received a phone call (the usual scam about "your internet will be down in 24 hours if you don't press these buttons") but the difference here, was that it showed as having come from my phone number. It hadn't of course. This is known as spoofing. It seems as if someone is hacking peoples phone book to get a genuine phone number that won't be blocked.
All my attempts at reporting this have failed.
