There are many many sites that were created in the late 90s early 00s on sites like angelfire, tripod and many other old "free" webhosts. A huge number of them are long since abandoned but quite happily sit there with their pr3+, DMOZ link etc... just begging for a backlink to your site to be placed. You're in luck! Many of these sites also contain long since abandoned email addresses from "free" webmail that again are just asking to be re-registered and a password remind sent to them! Its not easy work (i'm sure you can figure out a quick way of scraping them via scrapebox etc... ) but my sites have definitely benefited from this. note: you may be breaking the law by doing this, but the name of this site is Black Hat SEO!
