Open graph spamming, arbitrary rewards for inviting your friends, Facebook ads, cross-promotion, SEO... sounds exactly like Zynga.<p>Seriously though, hopefully this well shed some light on why Zygna uses the techniques they are known for -- they work. Amazingly well. Anyone who spends time in this industry discovers that pretty quickly. And it's really hard for upper management to see those upward kinks in the graph and say "please stop doing that."<p>The problem is that you have to become pushier and pushier over time and this leads to a slippery slope.
