The problem with this list in particular is that it's composed of user submissions on Reddit, where people probably only know their language + English + maybe a third language.

For example, "björntjänst" under Swedish. If you actually check the Reddit post, you can see that people have posted "niedźwiedzia przysługa" (Polish), "Bärendienst" (German), "medveđa usluga" (Serbocroatian) and "bjørnetjeneste" (Norwegian) as the literal same word. I can also confirm that the Finnish "karhunpalvelus" is also a literal one-to-one translation.
