Mitt Romney has gotten extremely popular on Twitter in the last 24 hours. In fact, he is receiving 25 new followers per second as I write.

What's happening? It seems to have started Friday, when Romney's typical average of 3,000-4,000 per day increased more than twenty-five fold to over 100,000 in a single day, according to TwitterCounter.com. But the new followers are highly suspect. From "empty" accounts to pornbots, spambots, Justin Beiber-related accounts, Obama supporters and foreign accounts, the followers tell a puzzling tale, suggesting spam automation, purchased traffic or perhaps even sabotage.
