= (originally Greek) activist "I don't pay" movement
"DEN PLIRONO is a movement that transforms revolutionary theory into everyday actions of resistance and solidarity. Our actions have inspired the creation of corresponding movements in Spain (“Yo no Pago”) and in Sweden (“Planka.nu”).
The DEN PLIRONO movement’s goals are to propagate ideas, ideals and ways of action throughout the Greek territory." (http://99getsmart.com/tag/den-plirono-i-dont-pay-movement-greece/)
