The world's largest pay-per-view content provider shows no signs of slowing its anti-piracy efforts.
Ultimate Fighting Championship officials today announced they have subpoenaed Justin.tv and Ustream.tv - two sites with user-provided live video content - due to their broadcasts of illegally uploaded content, including the UFC's pay-per-view events.
Zuffa LLC, the UFC's parent company, has served both sites subpoenas that demand they reveal the identities of users who uploaded UFC content.
