Perhaps off topic, but I've always thought that "debunker" is a very negative-sounding word. Yes, I get that it means "removing bunk", and that bunk is a bad thing, but the word itself doesn't sound helpful. Mythbuster is a better one, but that has been taken...
I think that initially the word can be a problem, but it's also an opportunity to explain what you are about. "Mythbuster" really suggests even more prejudging.
