Even though Viralg's technique of faking file hashes works only with some of the old peer-to-peer applications, such as Kazaa, it is nevertheless illegal to take matters into one's own hands when fighting against copyright infringements.

In his request for investigation Mr Sallinen reminds the investigators that action should be taken before companies take up a habit in defending their rights by illegal means.
