In retaliation, Anonymous has fired back. In a statement released today on Operation: Payback's homepage, Anonymous justifies their current target:
"The Federazione Industria Musicale Italiana (FIMI) is responsible for getting ThePirateBay blocked in Italy. Censorship is something used by fascists or dictators. Censorship is the opposite of democracy. With this act, the FIMI/IFPI is a threat to freedom. Everybody must realize that people will fight when they are oppressed, they will do whatever it takes to be free."
The "Low Orbit Ion Cannon" attack appears successful. At the time of this writing, all three websites are down - made significantly easier since they're all on the same server.
Current status as of 11 AM EST:
FIMI.it: Down
IFPI.it: Down
Pro-Music.it: Down
