Facebook reporting accurately is sane, but Facebook is in charge of what is being reported, which is not sane.
Like, imagine if your friend was slowly poisoning himself by flavoring his food with lead for a month. Even if he is honest with you about what he’s been doing, it’s still not a sane situation. If anything it’s less sane to be seemingly lucid and forthright about a month of self-destructive behavior, but not actually do anything to change it.
The question here is: why did Facebook allow the situation to get so bad that this page was the top for a whole month? Why didn’t someone at Facebook notice this stupid pointless scam page was surging and do even a little of research and tweaking to change that?
They have seemingly abandoning any responsibility for the behavior of the machine they built and operate. Personally I don’t give them many points for just reporting that.
