how, and more importantly, why this ended up in my FB feed?

Is this one of the "social media strategies" that agencies developed for brands to "connect" with consumers on social networks? And, why does it not offer the option "none of the above"? Out of sheer curiosity, I clicked on "Pantene" (no, I really don't care whether I can buy it online or not). As a result, I got a graph with the survey results. What does it do for the listed brands, beats me. As for what it does for me, it annoys me. [nonexistent option: "less about Sponsored Poll"]
