dzenrei (dzenrei art) looks fully AI gen to me. Random twitter account whose only contributions were reposting cutesexyrobutts' and shexyo's pictures until late 2023 suddenly starts dumping art of their own in those artists' exact style. All their images are artefacted and heavily upscaled, the most blatant example being post #8425958 where the necklace and body hair stubble stick out as manually painted on in the target resolution while everything else is a blurry mess.
There are way too many giveaways, and the two artists you mentionned aren't the only styles getting copied (post #8473740)
Honestly the highly inconsistent yet copied style alone is pretty damning, even more if taken with the context you gave about the twitter account
