If sharing is caring, and you want to show that you care, then popular torrent client uTorrent has a new feature that's just right for you.
Introducing uTorrent's new 'Altruistic Mode', which forces the client to upload twice as much as it downloads, when sharing files with other users.
While all users who use BitTorrent to download will have to upload at least a portion of the same file, users who wish to follow "good torrent etiquette" will at least ensure they upload as much as they download (a 1:1 ratio).
But those that want to be more generous will now have access to a new experimental mode in uTorrent that forces a 2:1 upload-to-download ratio.
There are some quirks to the new mode though, as it sticks so strictly to the 2:1 ratio that some downloads may never complete. But that may be of little importance to users whose main aim is to give back to the torrent community and ensure a healthy swarm.
Altruistic Mode is available in uTorrent 3.4.9 and above, and BitTorrent 7.9.9 and above.
