German and APT::Acquire::Translation
The webinterface for it doesn't require any authentication at all, leading technically to anonymous translations all over the place. The so-called "review" process consists of the same not-existing authentication, leading to a situation where unknown people can put in whatever they like and have other (or potentially the same) unknown people acknowledge that. The language team has actively chosen that way because it was said that bad translations simply won't happen and that the review (three people opening the page and clicking onto a button) will not let that happen. Well, it happened. And is happening all over the place.
Hmmm… That sounds quite like a definition of Wiki in my book. Just add a version-control layer underneath, and… Oh, you didn’t? Umh… Tough luck! :-(
