Here’s yet another example of why you need to think about what you post for public viewing on the Internet. The story “The family Christmas photo that became an ad for a Czech food store” demonstrates how once you upload your information to the Internet you have no idea how that information may be being used. It also shows how someone can use it for commercial purposed without acknowledging or paying you for something you created.
Generally most people would not hand over personal information to a stranger in the street if they were asked, yet they willingly do so on the Internet? How come? Seems to me, most people really don’t understand both sides of the Internet. Yes, there is plenty of good but there is just as much bad. The issue isn’t the Internet per se, it is the human beings that use it.
Value your privacy because the Internet sure doesn’t and once you surrender control of your information then it is lost for ever. Be ware!
