I looked at the submission and still have no idea what this is about, but thankfully your informative post filled in all the gaps.
I do my best, but in case I omitted any details in my last post, I shall clear the confusion. Tojyo is a Japanese Sonic porn artist. In Japanese style, he censored his porn. Pixiv is a Japan-centered artist website like FurAffinity (except run by competent people). He received a PM on Pixiv from a troll pretending to be an FA admin, telling him that he could not censor his art on FA--the troll probably assumed that he would uncensor all the porn posted on FA. Tojyo, not being a native English speaker, apparently took this PM at face value. However, rather than uncensoring his FA gallery, he deleted all the porn. All his FA fans are butthurt.
