The Lewdtuber/AVtuber thread by McKenzie is by far the most organized thread about lewdtubers in SC. You can always ask McKenzie in the discussion thread about someone not included in there.
The JP AVTubers list there doesn't look like a lot because the big AVTubers are usually a part of agencies like Tamapro, Emoechi, Masquerade, Connectopia, etc. which have their own threads. If you want, there are a couple of folders somewhere in this thread with more AVtuber content than your dick can ever handle.
Other than that, the case for AVTubers is a bit more complicated too, since some people discussed in this thread don't necessarily count as AVTubers. Nozomi, for example, is the PL of a regular VTuber who happens to do lewd things. I'm not even sure if Rika and Canan have L2D models.
