"This is a unique opportunity to test the effectiveness of leaktivism", said Micah White, co-founder of Occupy, "... the Panama Papers are being dissected via an unprecedented collaboration between hundreds of highly credible international journalists who have been working secretly for a year. This is the global professionalization of leaktivism. The days of WikiLeaks amateurism are over."
