Promusicae, the Spanish version of IFPI, has filed a claim in a Madrid court against the file-sharing website Blubster. The claim alleges that the site showed "parasitic behaviour" and that it had "commercial intent" with customers paying "from $10,000 per month" in advertising fees.

According to a report in the LA Times , Blubster added a "layer of anonymity" to its file-sharing service, so that it is harder for content companies to track what its users  are doing - and that may well be the real reason why they are prosecuting.  The LA Times article also points out that the case raises similar issues to the Grokster case in the US and the Kazaa case, which was pursued in the US and in Australia. 

 And as anyone in the media industry knows, $10,000 isn't much in terms of  advertising rates - on or off-line.
