I get not wanting AI images in Danbooru, but this has turned into a full-blown paranoia for some people.
It's not "paranoia" to point out that an artist accused of tracing and using AI assist before is still using AI, to most that would be basic pattern recognition. Especially when their artstyle began to change incredibly fast in tandem of said AI boom as a result after they were thought to be using it and never went back. Then suspiciously newly created accounts out of nowhere kept tag vandalizing any Shexyo image that was tagged AI on Danbooru and kept nuking his wiki which outlined his aforementioned controversies.
I don't believe his current works should be mass purged at all or anything, mind you, but just brushing off suspicion of a guy having a clear history and an out-of-nowhere artstyle shift as "paranoia" is bizarre. His art is clearly AI-assisted, it has resulted in a massive artstyle shift almost immediately and gave his current artwork a much cleaner look going forward.
