ohh yeah ask yourself how you promote pirated cds and other pirated stuff btw you can get linkbacks to yoursite using other forums .. that will draw lots of traffic to your site
Backlinks are good, its hard to do outright promotion since some of the things arnt legal. Tell your mates etc.. they'll tell theirs.
The URL is in his avatar. For warez, releasing cracked software and crediting it with your URL is a good way. Word of mouth is huge.
Keep taking Warez files off other sites, download them to your PC, then extract them, add password to them with the link to your Warez board, then you just need to upload them. Post in loads of other Warez Boards and yours and your url gets around!
You might be able to promote it on other more popular warez forums. Maybe try one of those dodgy affiliate programs...
