I'm pretty surprised by the lack of seeders. Out of the 2438 torrents listed, a third have 0 seeders, another third have 1 seeder, and all but 5 have less than 10. Hopefully the publicity boosts those numbers.
From what I've heard a good chunk of people rotate their seeds for LibGen because their seedboxes can't handle all the connections for every torrent at once.
I'm sure someone could get you the info to get setup as a seeder. For modern clients it's rather rather trivial to manage that many torrents. Get any decent modern CPU, 4gb+ ram, and $560 in storage and you're off.
