This is a great point; I'll edit the F.A.Q to reflect that almost anything goes.
I do absolutely want to avoid enabling people to depict creatures or concepts in potentially hurtful or harmful ways (or in the case of fictional IPs, in ways that the creator hasn't authorized -- which I realize is a very different thing, but still falls under the "almost anything goes" issue). I believe you, but would definitely appreciate a source to direct people to in case any jammers are looking for more information.
Thank you!! I'm 100% on the same page ^^ And here are some sources: an in-depth one about the wendigo in particular, a shorter one directly from a Native person, and a general explanation in the context of JK Rowling's blunderings.
