If you believe the original infringement ought be cited on a "do not feed the trolls" post, then you ought to bring it up in the review - or better yet, post it to the current Agreement thread so the mediator will be sure to remember the suggestion.
I will probably argue against your view though because I would rather not bring out all the dirty laundry every time we need to advise other posters that engaging a particular poster might lead to a flame war. A compromise solution might be a Freep mail to the newbies on the thread, but again it troubles me to speak behind someone's back.
Bottom line: the agreement is still quite young and subject to change and suggestions are much appreciated.
Sharks in the water signs, with people swimming in the surf is hard to imagine. I find your equivalency extremely weak and abetting of a well established tactic used to quell honest debate.
