Look, we already went through this crap with the Facebook Gold Account craze, or when people thought Facebook was about to charge them a monthly rate unless they posted something into their status. You might use Facebook as your personal social playground, but you don't have any control over your information; Facebook does. Anything you say or do on Facebook has absolutely no bearing on your account, your life, or the real world but to bounce around your friends' news feeds and stuff another nickel into Mark Zuckerberg's brimming coffers. The sooner you get over that, the better.
It seems as if the ol' super official privacy notice is making its rounds on Facebook again. For your edification, in case you were planning on posting it yourself, it does nothing. It may seem like it's legit because it's written in semi-legalese, but it's basically a glorified "keep off the grass" sign.
Author, Kate O'Neill used her platform on Twitter to encourage people participating in online activities like the recent, trending profile picture aging meme on Facebook, to slow down and think about it critically. O'Neill asks people to consider how willingly posting that information online for Facebook's seemingly sentient algorithm to digest, can have a ripple effect on society as a whole; how that information can be fed into worldwide databases, sold off to advertising agencies, and used to exploit the very people that upload it, without considering the impacts, in the process. She doesn't aim to inspire panic in this Twitter thread, but instead, she wants us to think critically when considering the fast-changing landscape of the world around us. Some solid advice!
