In these economic times, it’s a no-brainer: soak the fat cats. “Take from the rich and give to the poor” will win votes. That’s the idea behind film maker Richard Curtis‘ social media campaign to build public support for the Tobin Tax in Britain, also dubbed The Robin Hood Tax. Curtis – better known as the director of lighthearted romantic comedies like Love Actually and before that as a writer for Blackadder – created the campaign as a movement to reduce poverty and fund the tackling of climate change. Basically you can vote yes or no to levy a small tax on every banking transaction.

Yesterday, however, saw a fishy spike in the “no” votes – from 1,400 to more than 6,000 in five minutes, The Times reports. Even fishier was their provenance: most came from a Goldman Sachs server, the newspaper reports. This is just the latest in avalanche of bad press that the investment bank has been subjected to since the financial crisis began. Goldman Sachs has neither confirmed nor denied the act, though it is investigating. Meanwhile, accusatory Tweets pour down on the Wall Street behemoth.

Online vote rigging – whether the aim is to win a car or generate support for more substantive issues – is sadly a common occurrence when so much is on the line. Omniscience is not required to suss out a culprit, just a competent geek. But we don’t need to tell investment bankers this.
