Great script! But...
The torrent sites links are in dire need of updating.
Most of the public trackers are dead and should be removed.
Some have moved or were "resurrected":
KickAss --> Katcr.co
Rutor --> http://www.new-rutor.org
Torrentz --> https://torrentz2.eu
Some others to add (mostly Russian):http://tfile.mehttp://rustrek.ruhttp://torrent-pirat.comhttp://unionpeer.orghttp://pornolab.nethttps://zooqle.com
