No, the notion is that you, as the owner of a file hosting site, cannot reasonably tell whether a given copy of $something was uploaded with permission or not (nevermind that you aren't required to do so anyways)
And go pull quotes all you like, that doesn't change the fact that deduping means you pull links, not files. Full stop. It's not your job as a site owner to police copyright for big media. And if it was, it would be a full time job and then some.
You're the one who's completely ignoring my post based on a few cherry picked instances from a single DOJ case. (The cherry picking done by the prosecution, not you, before you think I'm accusing you of something untoward)
Go reread my post and tell me how I'm wrong, please.
... and if the owners and operators of MegaUpload were using it to share DVD rips with their friends, and stated explicitly in their emails that they knew the majority of their media content was infringing, your particular group of friends would be relevant... how?
Before you answer, consider whether or not I'll just be able to pull an email quote out of the indictment to make your objection look silly.
