As you might have read on Techdirt (and as I recount in greater detail in my just-published book), between 2010 and 2011, a dozen or so underfunded Mexican activists (with a key role played by artist and Techdirt contributor Geraldine Juárez) under the label of the Mexican Stop ACTA network and leveraging social media like Twitter, convinced the Mexican Senate unanimously to reject ACTA. Specifically, the Senate, which is responsible for ratifying international treaties, told the President they would not ratify ACTA if he signed it.
