I can't honestly say that this forum really operated much differently before reputation was installed, but I would guess that if someone has vastly negative rep, that it would be something the admins would look at, after all it isn't like anyone is getting paid to moderate this place, and many of us are hormonal, scared, and just new to this all so we are a population in need of much more moderation than most. So, if it makes the jobs of mods easier then I say keep it, if not then I really don't see all that much point.
