On the WvW forum on those threads that cover the weekly matchup, debate between the three servers can get pretty heated. I don’t know if there has been an active one that a moderator hasn’t had to close and clean or just lock at one point or another. If commentators had the ability to see that the majority of their peers down-voted an inflammatory comment, then they might feel less inclined to respond. Why point out how stupid something is when clearly everyone already knows. Hopefully this might prevent threads from quickly descending into trolling and sniping for a change.
There seems to be something already in place with the +1 thing, but I’ve no idea what that actually does.
