What I’ve found is that some dudes claim, that there are good private trackers for german dubbed content. Even for ebooks there are places it seems. But what i’ve seen to be more often claimed is that there are large usenet communities with all the content you want. With these though, you once again have to pay the community with money. Just like with the oneclickhosters. I backed all those comments up. if you want to read the original statements, i could dig them out for you.
Edit: using the word “claim” since i am in no private tracker, as they always were closed for new guys and the usenet stuff - i didnt have time to find out wich respects my privacy enough, when it comes to payment methods.
