Very Nice topic Arjay
Here is the one that is hard to believe,I found it weird
Printer manufacturers print invisible yellow dots on consumer's prints that check to see if a person is printing counterfeit money. If you call your printer manufacturer and ask them to "please stop spying on you", they will send secret services to your address to find out why you care about your privacy. Upset? You should be. The more people who call their printer's manufacturers and make this request, the more likely secret services will refuse to investigate.
