Hi there
If people aren't seeding then there is NOTHING you can do to increase the number of seeds except to post back on the site where you downloaded the torrent requesting more people to seed.
Now I don't CARE what you are downloading -- that's not my call to make -- but be aware that a lot of ISP's now CAP torrent download speeds - especially from well known torrent sites -- the users of those know what sites I'm referring to.
The only way around THAT problem is to sign up to a private vpn service that is also friendly to p2p activities such as
YourPrivateVPN | Privacy Solutions
Cheers
