People never know who is looking at them on Facebook.

Our parents? Our possible employer? Our college classmates? Or just any stranger who  search “people who eat ricotta with their fingers at midnight”(Sengupta, 2013)?

People, attention! Facebook is not THAT safe and secure as we might think. Somini Sengupta’s article Staying Private on the New Facebook, published by The New York Times, mainly says that Facebook’s new search engine now allows complete strangers to browser all the users’ profiles and get any information they want if posted. And, of course, allow marketers to show suitable advertisements.

Well, this might be an old “news” – it was posted in 2013. The privacy and ethical issues raised by the update of Facebook’s search tool, however, is still worth people’s deliberation.

As Trent mentioned in his blog entry Protecting Your Privacy on the New Facebook, “It is well known that Facebook generates most of its revenue from advertisements… In my opinion, Facebook has done nothing wrong.” I cannot agree more.

Milton Friedman said that maximizing the profit by taking any possible methods legally is the duty of businesses. If it makes people feel uncomfortable to expose certain information to the public, do NOT post it online first.
