Snowfoxofdeath is half a fake identity assumed by Snowy Foxes to make it harder for people she knows in real life to find her and half Snowy Foxes. As evidenced by the fact that SFOD starting posting pictures of herself in the Photos thread, Snowy later got kind of half-assed about the fake identity thing. When mysterious technical difficulties made it impossible to use SFOD, Snowy decided to use her new handle as an opportunity to be more straight with Tropers because it turns out most of her friends were already Tropers or lurkers. Oops. Now that the tech gods have given her access to this account again, she's ready to clean up some of the more outlandish claims.
TL;DR: Snowfoxofdeath was a compulsive liar.
