Unfortunately torrentz.eu takes a big hit to certain searches due to DMCA requests, it even says at the bottom of a page how many results have been removed. It's a real shame, and it would be nice to have an indexer on Tor or Freenet that isn't as susceptible to this sort of takedown.

There is a freenet site that lists torrents, magnet links and inserts the file into Freenet but they use the kat API so I assume it's dead too. It shows that a Freenet based site could be workable though.
