File sharing technology and peer to peer (P2P) software programs (i.e., BitTorrent, Utorrent, etc.) are not in inherently illegal, but what and how you share may be.
When you upload or distribute copies of copyrighted works, or when you download or acquire unlicensed copies of copyrighted works, you may be infringing someone else’s rights. This is true regardless of where the sharing occurs – e.g., UCLA’s residential hall network, UCLA's wired or wireless networks, or your own off-campus broadband connection – and it does not matter if it is with just with a few friends or the whole Internet. If you are infringing – even unwittingly – you can be subject to civil damages of between $750 and $150,000 per infringement and even criminal jail time.
