If any of your personal info is on the internet, it has already been saved where you cannot remove it. This is a personal conundrum I have been trying to wrap my head around, especially as it relates to pictures of my kids I'd like to keep offline (but other people take pictures of them and upload them, and it's too late at that point...) A company I'm familiar with was attacked by a blackhat. He sent the company owner all his personal information including SSN, address, etc. It scared the owner enough to pay off the blackhat, but he also asked the blackhat how he got his information. The blackhat sent the owner a website that you can go to, pay around $4 in bitcoin, and search for anyone's information.
