Real-debrid does filtering based on the torrent name. Media uploaded to usenet is already obfuscated and split into many tiny pieces, the location of which are stored in a .nzb file.
This means eweka can't filter downloads based on the title. Once media companies get a .nzb file, they can use copyright infringement notices to make usenet providers delete the files, but that does not work preemptively (like filtering based on torrent name).
