This ain't surprising to me. I saw the smellslikejavier username and I followed that dude. I am surprised that this dude was not called out yet on furaffinity.
FYI, according to who ever edited the e621 artist tag; the reason this artist went anonymous was because they're Russian and became afraid of the morality policing there due to the political climate. It sucks and this artist deserves better. The way they illustrate feet gets me off like nothing else. Also, thanks for uploading the gallery, there's art here that never found its way to e6.
