Most people don't like the neg rep they get... I don't know if it's the criticism or the fact that their rep score is being lowered, but it's one of those things that just causes issues. If there's really constructive criticism that needs to be expressed, even if it's just a line or two (though you'd think it'd usually be a bit longer), it can be posted, or PMed, or thrown on their wall. Why provide yet another unmoderated line of communication? Flame eachother off the forum, haha. We have enough features cluttering up the page as is (and probably more to come once we figure out the RPG thing).
