Aggregating information from online sources allows people you would rather know very little about you achieve the opposite. With several Social Media and email accounts coupled with other sources of information like eBay, there is likely more of you in cyberspace than you would like. Combining details from sites like LinkedIn and Facebook along with Google searches, a complete stranger can come to know you better than your own family. Be selective about what you share online and understand the size of your cyber footprint. Delete anything that is not absolutely necessary; not a perfect solution, but a good start.
