The government's "Do Not Call" list is worse than useless. I noticed that whenever I put a number on that list, I immediately started getting many times more spam and scam calls then I got before I put them on the list. It's obvious that that spammers and scammers use that list as a source of numbers to spam and scam... exactly the thing it is supposed to stop,
Don't put your number on that list or it will get worse.
I wonder how many billions of dollars of taxpayers' money is being wasted on that list and all the useless bureaucrats who run it.
