Might you have access to their content? The posts that get imported into Kemono refer to a "important" marked item, which within Kemono and their own Fanbox, does not seem to exist
I don't, nor have kept up with their stuff. This "important" item might have something to do with distributing works on Discord, which is an extra layer artists have been using since a while back to avoid their stuff being accessed from sites like Kemono.
But like i said, haven't been keeping up, so i don't know.
