I'd like if there was an option for my scanlations being open to everyone. I don't do my scanlations for money or fame, I want as many people to read them as possible. If only batoto members will be able to read my scanlations then that defeats the entire purpose. Who cares if other sites copy your shit? It was never yours in the first place. The mangaka and the publisher own the manga and all its derivations. Scanlators are just doing public service.
I agree with what you said, but I assume some want recognition of their work for their public service. So like you said, there should be an option for scanlations to be open for everyone and I guess in consideration of those that want credit to allow them the option for their scanlations to be private for users only on Batoto.
