Worth noting that DrunkenSlug is just the indexer. It doesn’t actually provide any of the Usenet access. Just like The Pirate Bay allows you to search torrents, but you need a torrent program to actually download anything. In order to actually use DrunkenSlug, you need a subscription to a Usenet provider.
You can come over to https://lemmy.dbzer0.com/c/usenet_invites and post a [W] for any indexer (popular ones are DrunkenSlug)
Otherwise if you want content in german language you can look up houseofusenet and see if you can register there.
