Most recently they have been bombarded by phone calls that show "APPLECARE" on caller ID.
Until STIR &/or SHAKEN is implemented, don't bother reporting the number to any relevant government body because the numbers are spoof. Do Not Call List won't make any difference if the scammers are from overseas.
These are some of the reasons why fed up people are doing something no government can do: Fight back. And one method of fighting back is Lenny.
I've had Lenny installed for a number of years now and the calls have dropped. I am lucky if I actually get a scam call a month.
