Hashes whether linked or not are still gateways to copyright content. What you're describing is not that different Google in some ways. ISOHunt tried to make the Google argument about just being a search engine... but the distinction is that your visitors come specifically for torrents (mostly of a copyright nature) and your index provides copyright content. Google on the other hand is a general purpose search engine where copyright infringement make up a small percentage of their search. Your site would have to be a general search engine site to have any compelling legal argument.
