Just goes to show, invest in some real marketing, make something really valuable to someone rather than relying on 'growth hacks' that tend to explode in your face.
How does this show that? All this shows is that there is risk do doing growth hacks. It does nothing to show if these hacks are worth the risk. Rap Genius, is, after all, the most well known and successful site for rap lyrics as far as I know, so (ethics notwithstanding) unless this kills their business, it was a smart move.
