Pirate Bay Scope & Torrent Lens

The technology itself is perfectly legal, but it has been debated if its implementation in connection with copyrighted material or otherwise illegal material makes the issuer of the bittorrent file, as opposed to the copyrighted material itself, liable as an accomplice or infringer.

Allows you to search torrents without opening a browser, and allows drag and drop to transmission for downloading. You can also filter by torrent type (music, video, ect.) and size.

sudo add-apt-repository ppa:scopes-packagers/ppa
sudo apt-get update && sudo apt-get install unity-scope-piratebay python-lxml
