stopped encouraging the F'U style posts inciting action against other authors, unless such posts are "Decline Payout" posts (such as this one)

Agree, except: I don't think we need F'U style posts at all, nor posts inciting action against other authors. We have a voting system, and if you don't like someone's work you can either vote for different work or downvote it. Attacks, trolling, F'Us, etc. have no positive role to play here.

And if, for whatever, reason you do see the need to go on these witch hunts, at least make sure to get the facts right, which probably should include actually communicating with the author getting the other side of the story before making accusatory and inflammatory posts about your concerns (if that had been done here, the entire false allegation about lack of permission and copyright infringement could at a minimum have been entirely avoided, and the lack of understanding of how an older photo of someone, who is now an adult, came to be used would also have been cleared up).
