I genuinely want to, but I can only stand doing Danbooru-style tagging for so long on a phone (Probably why my reputation there has since plummeted - literally almost halved), and I can only use SFW stuff on a PC. Not easily able to upload pictures either, unless maybe there's a source function.
I can at least tell you the Tenryu mud flat artist has a Pixiv here:https://www.pixiv.net/member.php?id=17558942
Finding the source for the images using SauceNAO might be a good start, if my hunch is correct and most of them are on Pixiv you could presumably translate the tags once you see the original post.
Danbooru/Gelbooru/SanCom duplicates should probably have their tags copied as well.
Admittedly I'm typing this from a literal armchair though, so it's not like anyone needs to take me seriously.
