Robocallers posing as FCC fraud prevention team call FCC staff

The FCC proposed a $4,492,500 fine against VoIP provider Telnyx after malicious actors using fake identities (the "MarioCop" accounts) placed roughly 1,797 prerecorded robocalls impersonating an FCC "Fraud Prevention Team" and attempting to intimidate recipients into payment; the FCC alleges Telnyx failed to perform adequate KYC checks, while Telnyx denies the claims.
