Can Facebook app developers see how many/which user-to-user messages from their apps are being reported as spam?

You can see this information through App Insights, under the News Feed > Spam tab. Replace APPID with your own Apps ID in this URL.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
