This is cool, but a lot of PR is even more devious! At my first job ever, I was sometimes paid to simultaneously ghost-write stories by executives, then pitch the stories to magazines. So, it was still crap advertorials masquerading as content, but even harder to detect.
I wonder if you could do a linguistic analysis to gauge bias and ad-iness, and show a score. Gather a corpus of paid advertorials and compare to ostensibly unpaid material.
At my company though, those articles are ghost-written, and then they ask every employee to retweet and share it on Facebook and LinkedIn. It hasn't gotten to the point where we get in trouble for not doing it, but I fear that point is quickly approaching.
One line that I won't cross is if they start requiring me to post to social media using my personal accounts, and I will change jobs over it.
