It seems like Facebook can’t wake up from this bad dream.

A new report published by the Guardian Thursday states in no uncertain terms that the social network relies on “human intervention at almost every stage of its news operation.” The paper published a 21-page leaked Facebook document showing guidelines for the social network’s news editors that include information about how they can “inject” stories into the site’s Trending Topics module under certain circumstances. Gizmodo made the same allegations earlier this week but did not publish corroborating documents.

A spokesman for Facebook told The Huffington Post that the Guardian’s report used an old version of the news editor guidelines. On Thursday afternoon, the social network published an updated and partially redacted version of its guidelines, along with a blog post offering some details about how the editorial process works.

The news that humans are crafting the feature is controversial for a couple of reasons. First, Facebook doesn’t mention anything about human involvement in its description of Trending Topics. On its help page about the section of the site, the company states: “Trending shows you topics that have recently become popular on Facebook.”

Second, and more damning, Facebook Vice President Tom Stocky said in a statement earlier this week that “We do not insert stories artificially into trending topics, and do not instruct our reviewers to do so.”

The documents published by the Guardian include details about how Facebook’s editors can do exactly that, as long as the topic is “appearing in the demo tool.” It’s not clear what that tool is.
