Well I think so, as long as it doesn't violate any copyright's it should be okay to host their release, but I can't say for sure.
It would violate copyright, but that copyright belongs to the creator and publishers, not to the scanlators. If this group doesn't want their releases redistributed without permission, maybe they shouldn't... distribute it on the Internet without legal permissions in the first place 
My bad, what I meant was blacklisted material on BBT, but I posted completely different to what I meant.
Ok, the manga isn't available anywhere. I have up till volume 2 but don't have have the last volume 3. So can I upload this, I need a mod to confirm.
I am saying cause this manga is an old one (1995), and finding the complete manga is not easy. And since this request has gone unanswered it seems others are unsuccessful in finding it either.
