The non-profit group CIAPC (Copyright, Information and Anti-Piracy Centre) took the website to court in Helsinki last year on behalf of a Finnish recording industry association.
The court controversially ruled that Elisa, one of the largest telecoms operators in Finland, must block access to the website.
Elisa complied with the ruling on Monday, and CIAPC said it received an e-mail signed by Anonymous Finland shortly afterwards. This said CIAPC's office in downtown Helsinki would be bombed this week, according to CIAPC, which has reported the e-mail to the police. http://www.reuters.com/article/2012/01/10/finland-hacking-idUSL6E8CA38H20120110
