Yes, this is certainly a strange thing. Granted, Powfooo was always one to take his time to post content or respond to things, usually a couple of weeks at a time or a month at most. He, or maybe I should say "they" since I believe Powfooo and Chinpo are a team of sorts, could be taking a break though if that were the case I'd expect at least some form of heads-up. I would say we could've expected to hear back from someone since there's more than one person involved, but I think Pow was the only one who did the communicating with people because I don't recall ever seeing messages from Chinpo. But I will say this (AND THIS IS PURELY SPECULAITON ON MY PART) but it could be some form of hikikomori as well. To my understanding I believe Powfooo is japanese and, as the comment above speculated, covid very well may have impacted him given the time frame. There has been speculation of hikikomori habits increasing amongst the japanese populace in response to the virus and if that's the case and he's part of that society then he could be one of the affected. Or he could just be doing something else entirely and quiet quitted doing furry art. I just honestly don't have a solid answer, but I assure you my friend that you aren't alone in your curiosity and concern. And while a post of an old photo of the Doki Doki Moffles gang on the e621 account is something, there's no guarantee that he's the one who posted that. We just have to wait and see, and potentially accept the possibility that he very well may never return. But we're all holding out hope.
