Speculation on various blogs states PSI may be associated with MediaDefender "a notorious anti piracy gang who have worked for the MPAA, RIAA and several independent media production companies." (Ref)  This particular post goes on to say that they "just launched their very own video upload service called ‘miivi.com’. The sole purpose of the site is to trap people into uploading copyrighted material, and bust them for doing so."  Ugly.

If it is in fact these snoopers visiting my blog my guess is that it’s because I have my own, self created, me as artist MP3s with  metadata on my blog. 

Chasing down MP3 users by scanning websites for MP3s seems futile and like a stupid waste of time.  I resent that by merely using MP3 technology, my site’s been targeted for snooping.
