Our advertising the mangaka's Fanbox is an attempt to further advertise for the original creator so people might give them money.
Some groups will take the content from the artist Fanbox and scanlate it to be put up on Dex. Personally I didn't feel morally in the right to do so for this series...
My group will probably work on it when we finish one of the series we're currently working on. We're actually working on the sequel series to the one this is a spinoff of. So if you're interested check it out.
