Looking back it seems many in the Japanese community on Twitter aren't happy with discovering their art is being used as training data. In the last week since the NovelAI announcement the number of banned artists on Danbooru has doubled, approximately the same amount as all the banned artists that were registered in the site's entire history.

Beyond the training issue there is the fact that the art was reposted on another site at all, which is what many take note of. It seems Danbooru's initial statement to Japanese users made it seem like it was NovelAI's fault that things blew over, without bringing up the reposting part that was the root issue, and it didn't seem to be an effective apology as a result.
