Skepticism is warranted when It comes to Facebook likes

$50 for 1,000 likes: Facebook likes are so valuable to people promoting products, songs and movies that a thriving business known as “like farming” has sprung up, and you can buy 1,000 likes for $50 (same price for 5,000 Twitter followers or 200 Google +1s). In a study reported by Pacific Standard, researchers who paid for likes found that unlike real likes, fake likes tend to rush in all at once or in blocks of a few hundred a day, and fake likers are generally older. Also, in comparison with real likers, a higher proportion of fake likers are male.
