Former prime minister turned banana-state bomb-thrower Kevin Rudd upped his attack on the Murdoch empire today by calling for a consumer boycott on, the property listing site which -- in case you didn't know it, and not many do -- is majority owned by News Corp.

Following the playbook of groups like Sleeping Giants, Destroy the Joint and Mad Fucking Witches, Rudd has gone full consumer activist tweeting: "Money is the only language [Murdoch] understands and @realestate_au is the financial heart of his empire."

Rudd's strategy is a departure from the usual call to boycott News Corp newspapers. Will it work?
