@Venetia: I think you at least got the second paragraph wrong... first and foremost, if you are aware that the file you upload will be accessible to others, it's not exclusively the filehoster's concern, but yours. Then, you are of course allowed to create backup copies, but you're not entitled to backup copies you didn't make from the media you own. In other words, owning Bad Boys II doesn't allow you to download the movie online, unless it's the very same you ripped and you uploaded (the part you're right with is that it's non-proveable, of course). And yeah, damage isn't just coming from people who watched the movie, it's from everyone who downloaded it - it's like you buying a DVD and not watching it - you still payed.
Basically, I agree with the rest though ^^
