I don't know if this would cause a flood of harassment, but are there any SMF settings or mods that allow people to see who is giving them +/- ratings? So if there, was, say, one person who just kept laming the same 2 or 3 people every 24 hours, we'd know who was doing it? Or, even if YOU (re: Arbie) knew who was doing it? Because, well, that's pretty fucking lame to do that to someone for something like a personal grudge or to be a dick.
Just thoughts.
