This article complements the two comments I made on my previous post.

I said:

With Megaupload closed, should you backup your online backups?

Answer:

In short, if you stored important files on Megaupload, I really hope you had an up-to-date backup on your computer.

And then I said:

Also: will this takedown have an effect on the users? Are we gonna see the RIAA or MPAA sifting through the logs and suing en masse?

This what the article hast to offer:

It’s almost guaranteed that Megaupload stored the IP address of file uploaders, and the Feds could pursue individual copyright infringement cases at a later date.

Choose your acronym: RIAA, MPAA, FBI.
