Here you go mate. It's pretty straight forward
What is the minimum
ratio I should keep?
Every user is expected to maintain an overall site
ratio of 0.4 after downloading 6GB. If you fail to do this the site will automatically warn your account and you will have 6 days to get back to an overal account
ratio of 0.4 The warning will automatically be removed as long as your account is still over the 0.4 minimum site
ratio as soon as it expires. It will NOT remove itself as soon as you reach a
ratio of 0.4
There is also a per torrent minimum which is also 0.4 If you are not able to
seed the torrent to 0.4 then you will need to leave it seeding for 60 hours within a 72 period (Ideally 60 hours straight) or you could receive a warning for Hit & Run.
