Members-only music-sharing site OiNK was shut down yesterday by British and Dutch police as part of an Interpol investigation. Police arrested a 24 year old man from Middlesborough, England, raided the man’s employer and home of the man’s father, and seized OiNK’s servers in Amsterdam. OiNK, a BitTorrent tracker, “hosted hundreds and thousands of torrents with over a million peers” and was a popular source for leaked pre-release albums. It’s invitation-only membership policy gave OiNK cachet and, ostensibly, greater security from music industry attack. No more. I’m curious to know more about how Interpol built its case.
