The list I gave was of some public trackers, I made no claim that they were zero knowledge trackers, I simply made a statement that trackers needn't be aware of .torrent file manifests in order to share peer lists.

I also indicated above that having knowledge of .torrent manifests is problematic as that doesn't provide real actual knowledge of file contents just knowledge of file names ... LatestActionMovie.mkv might be a rootkit virus and HappyBunnyRabbits.avi might be the worst most exploitative underage pornography you can think of.

Some trackers are also private and require membership keys to access.

I was skating a lot as TZubiri seems unaware of many of the actual details and legitimate use cases, existing law, etc.
