4shared, one of the largest file-hosting services on the Internet, is building its own 'fingerprint' database of pirated music.

In 2015, a coalition of copyright holders lost a court case which demanded an ISP blockade of The Pirate Bay in Sweden. A year later and Universal Music, Sony Music, Warner Music and Nordisk Film are back, hoping for a victory in a brand new court that could open the floodgates for widespread website blocking.
