from the top of my head:
1. put the affiliate link in an ebook and spread it using all the methods u can think of: make a half decent ebook from PLR products, insert your link in it, make a squeeze page, make a sales thread on DP, contact a few DP member to review your product before you start "selling" it, you can even make a few sales, but if not it's not a problem, that's when the warez forums and torrent sites come handy, just share your ebook there along with he link to your squeeze page, because it will "sell" better, if they see it's not free
2. use social networks: build targeted twitter following base, build trust/make friends, make them sign-up under you (you can trick them on the same way you do it with the warez forum visitors, see above or figure out something even better, be creative)
3. watermark a video with your link and put it on youtube, use proper tags, you can buy views to jumpstart your vid
4. forum signatures: you can buy signatures of well established accounts or built them yourself to seem more credible and after building some rep, put your affiliate link in your signature
...
other than that, use the search/browse the Affiliate Programs section what others already recommended
