Is there anything to explain ?
Well actually that's just an accumulation of stupid things they can think about... Yesterday, they voted a law that punishes illegal downloading. Way it works : you download Kill 'em All -> they find you (ok, this is NEVER gonna happend, but anyway) -> they send you a letter -> you download Ride The Lightning -> they send you another letter -> you download Master of Puppets -> they send you ANOTHER letter, but this time, that's the kind of letter you have to sign for (recommended, don't know the word) -> you download And Justice For All -> they finally shut down your internet access, including TV & phone.
