I feel like this is violating the rules, specifically "Duplicate releases are not allowed" and "if you are not part of the scanlation group, do not alter the release you are uploading by any means". The scans itself are clearly those of S.A.D., but they were colored in and the credit page was changed. If these colorings were done with specific permission from S.A.D. it should be credited as such. If not - well, this would be all kinds of bad.
