Startup Idea : Credit Card Issu

There are many websites who take your credit card details,like name , cvv , expiry date and so on. And thanks to the google web crawler often they are uploaded to google. Today i also got some websites where they are providing real credit card information. and i tried to check if it is blocked or not. so i tried it but thanks to god it was blocked.I think government of all the nations should stop sites like that which share credit card information like this. So it is my suggestion that you should not show your card to anyone, or if it is lost you should block it as fast as you can. or any one can do wrong thing with it. Thank you.
