This is typical idiotic behaviour of artificial intelligence systems which were incorrectly configured by incompetent junior engineers who might have no real-life experience.
For example, my publication, ILLUMINATION published hundreds of stories about equality and racism. These are high-quality articles curated by Medium and distributed to topics for the enjoyment of thousands of readers. All these stories demonstrate views against racism but Facebook, ironically, labelled my publication as racist.
Many writers send appeal messages to Facebook. I hope some smart executives in #Facebook can understand the concerns and ask their engineers to reconfigure their #AI systems.
I am very disappointed to read that your remarkable scientific stories are rejected by Facebook. I hope the problem is resolved soon.
