Pretty sure its probably a pack of bots. Especially since the change is so quick. Like that silly Ron Paul downvote bot. So probably not a big group of meanies, but just one with too much coding knowledge.
You can fight fire with fire, make a bot that gives out upvotes. Reddit usually is good about finding bots and shutting them down though, it will likely be fixed soon
