Facebook, Friend or Foe?

Youtube science channel Veritasium, recently did a rather somewhat interesting yet disturbing insight into the world of Facebook advertising for your business, or not so legitimate business in some cases as pointed out in the video.

After watching this, you really have to ask yourself, is the legitimacy behind social media marketing really all that it is cracked up to be? Do you have any luck with your paid results? to the point that you get a return on your investment.
