I just noticed that for some reason there is a german tag. It seems rather pointless to me and thus I would suggest to remove it.
You're absolutely right, of course. We're blacklisting the german tag internally, effective immediately, so people won't be able to create it anew in the future.
The german tag was introduced a long time ago (don't know who did it) and many people used it. I remember Takkat asking the very same question in chat a while ago. At that time, he removed that tag from any questions that were using it.
I'm afraid but people were using it again of late. Unfortunately, we cannot ban this tag and it's easily recreated any time.
However, it doesn't make sense at all, and we should remove it from all questions.
