Judging from this artist's recent twitter activities, they to have been forced (directly or indirectly) to stop drawing altogether out of fear of being mistaken as real paedophile, possibly by people the artist knows. The artist then skipped both Houraigekisen and C96 because of it.

And yet they haven't seem to have drawn any R18, loli or not. Wow.

ETA: Or maybe they have it just wasn't uploaded.

Not uploaded here, yes, but the artist have published a couple R-18 books, the last one IIRC involving Tatsuta K2 and shota Admiral. I can't freely access pixiv/niconico so I can't determine if the impetus was from there instead of IRL.

Something definitely happened between May and early August and certain tweet implies that the artist was already having difficulties with their next book before the issue came up.
