An ISP is not a court.
The saga continues, with the music industry attempting to subvert the law in Europe and turn ISPs into policy enforcers and courts of law all at once. With ever higher profits in 2008, and a pretty grim record of accusing and prosecuting the elderly, single mothers with no computers etc. in the States, it seems like the music industry would rather hand the dirty job over to ISPs.
This is, besides illegal, pretty prone to error --- as history has shown. I'm really looking forward to the next settlement Eircom will reach, this time with wrongly-accused (and disconnected) individuals. Hopefully it'll be more than enough to compensate for their stupidity.
