torrentleech is wrong.

From their wiki:


Seed a torrent to at least 1:1 ratio
Seed a torrent for at least the minimum time required for your class in total. Be aware that seeding time only counts for fully completed torrents (downloaded 100%).
Not following this rule will trigger a reminder and eventually an account warning, which in turn can lead to your account being disabled. Read more about these below.

How long do I have to seed a torrent?
The time you have to seed a torrent for varies per user class. The so called seeding time only goes into effect on torrents you have downloaded fully. Partially downloaded torrents will never accrue seeding time and need to be seeded 1:1.

User class Minimum seeding time
Registered 10 days
Power User 8 days
Super User 7 days
Extreme User 6 days
TL God 4 days
VIP User No minimum seeding time
