Fake news detector for Facebook leads to fake news story about who made it

BS Detector was created by Daniel Sieradski (not Facebook) and was a reaction to the network's failure to flag false information - until Facebook blocked it

It's a fable for our times. Someone creates a tool that flags fake news on Facebook with big red warning signs. Someone else installs said tool, forgets about it, and then mistakenly assumes that the red warning signs are evidence of Facebook's own efforts to tackle the problem. A reputable technology website then writes a story about Facebook's new experiment without doing any fact checking, thus generating its own piece of fake news. The icing on the cake? The fake news detector fails to recognize it as fake news.
