Which public wall are you referring to? I only know that he posts on Bluesky and Twitter, the rest is paywalled. He pretty much never posts QoS publicly. If you've seen QoS stuff on rule34 or other booru sites someone probably leaked it or these are third-party edits. There is a guy on e-hentai taking care of the raceplay galleries and he updates it occasionally, but the galleries are not maintained by Nyantcha
The last QoS post he posted publicly that I can remember was more than a year ago and even then it was subtle
Someone sent the proof already. You probably missed it:
