It turns out that the MPAA obtained an injunction on October 16th for the Popcorntime.io site. The lawsuit accuses the devs of copyright infringement and also names the service's VPN provider, VPN.ht. At the same time, the MPAA was threatening a multi-million lawsuit against the alleged operator of YTS, who lives in New Zealand.
"This coordinated legal action is part of a larger comprehensive approach being taken by the MPAA and its international affiliates to combat content theft," MPAA head Chris Dodd touted. "Popcorn Time and YTS are illegal platforms that exist for one clear reason: to distribute stolen copies of the latest motion picture and television shows without compensating the people who worked so hard to make them."
There will surely be more information to come.
Here is a New Zealand article about the take down of YIFI - who turns out is from New Zealand.
