You might want to look up "decimation". I'm just sayin'. Oh hell, look up the past tense, "decimated" while you're at it.Furthermore anyone summoned should counter sue for court fees, decimation of character and lost time at work.
This wouldn't happen if you were running proxies and peer-guardian
But the smartest thing to do in this case is to ask for proof that you were the one who did the downloading and not someone else piggy-backing off of you. Either the lawyers will ask the court to shell out money for warrants of hard drive seizures or they'll all just say "you know what? Don't worry about it. They're right. We have no proof it was them." Just think about how much money and time would be spent on getting warrants approved and then going through all the info on all those hard drives. It just isn't worth it. Unfortunately, if you caught downloading, you most likely aren't smart enough to think of this, lol.
