I'm not sure, really. I assume that it would probably be mostly "theory-less" in practice. Google built ways of accessing web page quality. This seems somewhat related. pagerank? amoorthy's project seems to be citation-based. That sounds like a good start, I think.
From what I hear, FB are now pretty worried about fake news and other issues relating to the last US elections. I suspect they're also going over a few other big political events where FB played a big role. After seeing it happen at home, it probably feels more real. Brexit. The Syrian protests, later civil war. ISIS. The Turkish coup attempt. FB played a bigger role than any other media in all these.
I suspect what they are doing about true fake news is probably spam filtering.
What I'd be interested in seeing them try is the stack overflow approach. Have a subjective opinion about what a good contribution to FB is. Design features to promote that kind of content.
