said by MooJohn:Because everyone must bow down to the Church of Copyright. Infringement is the new heresy and it must be stamped out at all costs or the world will descent into chaos!!!
I've said it before: why do we accept the word of any interested party when it comes to who is infringing? We wouldn't believe them if they claimed to spin straw into gold so why would we take a list of IPs based on their word?
You can't supply the court a list of license plate numbers and say "All these cars were speeding this morning. Cite the owners!"
