This is the definition of Piracy from the MS Word dictionary. This whole "piracy" thing confuses me. Downloading movies, games, programs, etc. from p2p networks is considered as piracy but isn't everything downloaded from p2p networks illegal? Many people use these networks to look for songs to burn onto a CD and sometimes they ask someone on the forums if they know of anyone who has a particular song they're looking for and they never get into trouble but when someone asks about a movie their post is edited because they were talking about pirated material. I have nothing against people who want to download illegal porn, songs, games or whatever. If that's what they want to do then all the power to them. I just find it odd that someone asking about a movie they were trying to download would get scolded from a moderator for talking about piracy yet it's okay to download copyrighted songs.

This whole thing is just way too screwed up!
