What are you wailing about? RWP is still in good standing. If he chooses not to participate, that is his choice (this has happened before).
Yes, when an oddly privileged few are permitted to poop in the punchbowl (including the supposed no-no of reposting their own deleted harassing posts), some people will leave the party of their own accord. I'll anticipate a counter-argument and say that allowing such conditions to continue is purely a management decision. Still, it bites really bad.
