I have been watching scambaiting videos on Youtube, they are hilarious. They tie up the lines and waste the scammers' time.
The IRS will not call you and request Itunes cards.
The federal government is not sending you any grants.
Anyone who says they can fix your computer, who calls YOU, is a scammer.
Any "advance fee" to get a lot of money is a scam.
If you give anyone money through Western Union, or MoneyGram, or read them the numbers off the back of a gift card, you might as well be throwing your money away and you won't get it back.
