They are running tests most likely. I've seen some other Fanbox stuff getting imported, but it's also not complete, and only a few updated artists have had their "updated date" set to present day, despite having some imports. They don't want people getting pesty when imports are broken, so sorting by date updated doesn't return much of what's up-to-date. It's a good sign that some stuff is being imported. Maybe it'll be functional mid/late January.
Unfortunately, it looks like no one has imported KelvinHiu to nekohouse.su. For those unaware, while it is very slow to load, they have a functioning Fantia and Fanbox importer, but they're missing a lot of what Kemono has. I've gotten a handful of stuff over there the past few months, but it still pales in comparison to the flood of imports Kemono will get when it's importer gets fixed.
