Barcelona-based Carlos Sánchez Almeida, a veteran of Internet privacy and piracy fights in Spain, says he’s upset at the move because it endangers the legal contents stored in Megaupload, now inaccessible for company customers. In a post in his Jaque Perpetuo blog, he’s recommending that Spanish users of the service gather information about the files they may lose due to the FBI shutdown, in preparation for a legal claim.

I'm concerned that the MegaUpload takedown might have violated the US Privacy Protection Act. I'm not sure how much legitimate use of the service there was, but there was definitely some. The wholesale takedown of the site presents some challenging questions.
