When the New York-based band Spirit Animal released "The Black Jack White" last spring, the band's frontman didn't have high hopes about the streaming music service. He loves the platform and subscribes to it but didn't think Spotify would help his band this early in its career.

These are the kinds of ethical dilemmas that tend to crop up when your editorial output is based in part on finding and sharing - and benefiting from the traffic generated by - viral content, the way it is for outlets like Gawker, or BuzzFeed, or Upworthy.
