Bad headline. The end of the video, discussed here [1], concludes that the problem is that clickfarms masquerade their activities by clicking on random ads. The problem isn't that Facebook is scamming, it is the scammers scamming Facebook.
Wasn't the conclusion more that the scammers are scamming Facebook but Facebook isn't doing much/anything about it perhaps because they are benefiting financially from it?
In reality, the researcher doesn't say by any means that FB is scamming advertisers. He merely explains and exposes flaws in their algorithm. The headline is flawed in my opinion.
This lost all credibility when it said "Facebook is rumored to be worth somewhere around $100 billion." First of all, a public company has a specific value, it isn't rumored to be anything. Second, the current value of FB on the market is north of $160B.
The title is a bit of a link bait, the video which was posted in an earlier thread (https://news.ycombinator.com/item?id=7211514) stated that, through Facebooks paid ads you also get likes from click farms (presumably because click farms like pages they aren't paid to like in order to avoid detection).
This means that a higher percentage of your likes are from click farms than if you gained your likes organically, so when you pay for a post to reach a set number of your fans, a larger percentage of that is lost to click farm users who you don't want, than if you had purely organic likes.
Too bad I can't downvote this junk.
