What is ACTA?
ACTA is an international trade agreement currently being negotiated by the European Union, the United States, Japan, Canada, South Korea, Australia as well as a few other countries, whose aim is to enforce copyright and tackle counterfeited goods (hence its acronym: Anti-Counterfeiting Trade Agreement).
The main problem with this treaty is that all the negotiations are done secretly. Leaked documents show that one of the major goal of the treaty is to force signatory countries into implementing anti file-sharing policies under the form of three-strikes schemes and net filtering practices.
