SCAMMER! id*ot with an accent told me my Facebook account had been hacked. He tried to talk me through some dumb thing on my computer to run some dumb program. I played along, but I wasnÒ€ℒt even sitting anywhere near a computer. He kept saying Ò€œWhat do you see on the screen?Ò€ I kept saying Ò€œWhat should I be seeing?Ò€ He kept repeating, I kept repeating. He finally said to tell him the letters on the screen, so I told him Ò€œF ... U ... C ... K ... O ... F ...Ò€. He finished the rest. I told him he was a piece of sh*t and berated him. I have no idea why he stayed on the line, but he did. And he kept saying that what I was saying didnÒ€ℒt offend him. I finally got bored with it and hung up on the piece of sh*t.

A political robocall doing a survey trying to find out if & how you are going to vote. Why would anyone disclose such information? And I hope the girl on the recording has another profession because her voice is mousey & annoying. Politicians must know how everyone hates these calls, but once again, they don't care.

Common Spam Call Types
in United States

  • IRS impersonation calls demanding immediate payment
  • Tech support scams claiming your computer has a virus
  • Social Security scams threatening arrest or suspension
  • Fake package delivery texts from USPS or Amazon

How to Identify Scam
Numbers

  • Caller claims urgency or threatens consequences
  • Requests personal info, PINs, or OTP codes
  • Offers that sound too good to be true
  • Unknown numbers calling repeatedly

Are Unknown Calls Always
Dangerous?

Not all unknown calls are harmful. Many legitimate callers include:

  • Delivery services confirming orders
  • Banks calling for legitimate verification
  • Medical offices, pharmacies, or hospitals
Pro Tip
Register your number on the National Do Not Call Registry at donotcall.gov. The FCC requires carriers to use STIR/SHAKEN technology to verify caller IDs. The IRS never calls demanding immediate payment - they always send a bill by mail first. Report scams to ReportFraud.ftc.gov.
