While it's interesting that Facebook wants to give a few more choices for those who respond, I think for most social media the only buttons needed are "trolling" and "not trolling." Of course pressing "trolling" would display a random hurtful comment that only the troll can see, but will lock them out from further comment on the thread. That way trolls can save time from their busy day of thinking up hurtful comments, and posters who actually receive replies that say "You are fat!" "You are ugly!" "You should die!" and "&%#*$^ you!" can assume that they are only constructive criticisms from non-trolls.
