If you run a file storage system with a deduplicating filesystem and you "delete" a file, you'll end up only deleting links.

There is no guarantee that another copy of the same file is infringing.

You don't need a guarantee, Megaupload is already passing the buck to the content provider who requested the takedown. Megaupload has a TOS to protect them in the event that they takedown a legitimate file.

I estimate the chance of a legitimate file being deleted by this process at 1% or less.

That's not very comforting for customer who might want to pay to store files there.

Especially not given the long stream of high profile cases of mistaken takedowns at sites like Youtube.
