@sssr:
And why not? It's no more or less a copyright violation than a regular scanlation. XD Whatever your opinions might be, on that front.
It's considered a
faux pas to poach other
scanlators' stuff but those rules, at the end of the day, have more to do with the community getting along with itself than they do with fundamental fairness.
...That said, no one likes flipped scans. But that's an entirely different matter.
