It's simple. Just register here https://www.seedr.cc/?r=502546 (You'll get 500MB boost ;-)) or here https://www.seedr.cc/.
Copy an address for a torrent from the address bar or right from the magnet link.
Insert it here
Click on + and then Add
Wait for it to download and then move your cursor over the folder, Buttons will appear and you can download everything within the folder as a zip file, copy or delete it. You might also just click on the folder and download only some of its content.
Everything is through the https protocol and that means your ISP has no idea what are you downloading. You can upgrade to several paid plans for increased storage, more slots, speed etc. or get some bonusone.
Adding your own torrents is also possible but I have yet to use this option.
Enjoy and support the authors of the stuff you enjoy ;-)
