There are definitely privacy issues with new media. Social networking sites might be the ones that are most subjected to this. For instance, people upload a vast amount of information on facebook, including one's birthday, occupation, address, and phone number. Not to mention the loads of pictures people post on their page. If you've ever tried it, it's quite easy to check out a strangers facebook page with just clicks of the mouse. The reason for this is because people either don't know or don't touch their privacy settings.
Users do receive a notification about changing their privacy setting from facebook, but this usually goes ignored. I believe the reason for this is because there isn't much emphasis on the notifications, it's just a small pop up text, where you can easily ignore it. I don't know the actual numbers but identity theft and scams must be at an all time high because of these privacy issues. Although new media makes life easier, it also makes negative things easier as well.
