"In a response Buma/Stemra issued a press release stating that their IP-addresses were spoofed. A very unlikely scenario, but one that will be welcomed by BitTorrent pirates worldwide. In fact, they’d encourage Sony, Universal and Fox to say something similar. After all, if it’s so easy to spoof an IP-address, then accused file-sharers can use this same defense against copyright holders."
This is quite a smart move. Getting these big organisations to explain this away will only add credence to the valid reasons that the public should be able to use to protect themselves. It doesn't matter what your personal opinion is on the morals of the situation the plain fact is an IP is not a person and the clearer this is made to the judges the better.
Of course there is a the chance that the IPs were added manually by the guys who set the project up, they already admitted that there is still test data in there (do a check for 192.168.*.*) so it's far from perfect.
