I remember having a defective hdd in my PC. I brought the pc to the shop, where I bought it from to get it replaced under warranty. They told me they couldn’t restore my data (I had backups) and asked if I wanted them to install windows on it. When they asked for my key I was like “FC…” and they responded “ok, we know that one, no need to spell it out” and proceeded with the installation
The first one kinda works, but I think it’d be more clear, when used without “selbst”/self, as this would be read to reference the invention instead of the inventor.
On the other hand, that then feels like “yeah, it didn’t work. The invention misfired and is crap”. Maybe “Erfindungserschafferzerstörer”? (Invention’s creator destructor) but that sounds off, too.
There’s not really a word that I can come up with that really conveys this meaning. There’s a german saying “wer Andern eine Grube gräbt, fällt selbst hinein” (he, who digs a hole for others, will fall into it by itself). Then there’s the humorous “Rohrkrepierer” (along the lines of “died in the barrel”) which basically means something like “dead on arrival” / that went wrong and didn’t work. So it’d be probably something that references one of those, which would make it work culturally?
Alternativ gibt’s auch noch andere Webapps, wie bspw https://feddit.burningturtle.win/
