Major Fines — The FCC has taken aggressive enforcement actions in recent years against telemarketers for apparent illegal caller ID spoofing and robocalling.
These included the largest FCC fine ever – $225 million – against Texas-based health insurance telemarketers for apparently making approximately 1 billion illegally spoofed robocalls...
a $120 million fine for illegal “neighbor” spoofing by a Florida-based time-share marketing operation
an $82 million fine against a North Carolina-based health insurance telemarketer
a $37.5 million fine of an Arizona marketer which apparently made millions of spoofed calls that appear to come from consumers
The FCC also proposed a $45 million robocall fine – the largest ever under the Telephone Consumer Protection Act – against a company that conducted an apparently illegal robocall campaign to sell health insurance under the pretense that the annual enrollment period had been reopened due to the coronavirus pandemic
Fines aren't working. Legislation that makes spamming a criminal offense and puts spammers, both domestic and foreign, in prison would serve as a better deterrent IMHO.
