tvtorrents.com has a credit system, you must have positive credits to be able to download
form the F.A.Q:
When you upload,
seed or share your file using the TVTorrents torrent file and
tracker, you will get credits. If you're seeding you will get 1.5 credits for each byte uploaded (3 if a Premum Member). If you're downloading you will get 1 credit for each byte uploaded in the same torrent.
For example: Seeding 1
Mb will give you 1.5 Mcredits, or download 2
Mb and uploading 1
Mb will deduct 1 Mcredits from your account.
When there are 5 times more
seeders than downloaders in a torrent, download only costs half (i.e 1Mcredit deducted for 2Mbyte download). But in those torrents no
seed bonus will be given, so seeding will be 1:1, 1Mb upload gives 1Mc (premium still has double for seeding, so they'll receive 2:1).
