Are you choosing torrents that people want?
Do you leave your torrent client running with the files you have downloaded after the download is finished? Sometimes poeple will come to them a while after you think all interest is gone.
Have you tried picking some freeleech torrents? But make sure there is plenty of time left.
And don't forget uploading (seeding) is slower than downloading.
And get some bonus points by joining in the forum, adding pictures to torrents or voting on your downloads (you haven't made any category votes - you can make them even if a torrent already has a category).
Post your own torrent (search for duplicates first)
