We'd pay, they'd sell; how come this hasn't been monetized?

My big question/looking for suggestions is how to address this issue? People would definitely pay for this kind of service, and (I would imagine) authors would love to earn some revenue.

Is it because of language barriers? Outdated "legacy" practices?

What are practical solutions? I can't even imagine what a good way to monetize this would be (grooveshark style?)

Manga Artist Park Jin-Hwan Speaking: [...] But I saw 'the breaker' uploaded on a foreign website. It's being uploaded with only a few days delay. What's more surprising is that everything has been translated (even these notes from myself). So, I'm now speaking to that group. Please stop... Why are you selling and profit off our work?

So please stop. Take them down before it becomes a bigger problem!!

We, like countless thousands of other people from around the world, love your work, and always look forward with anticipation to the next chapter. We would love to continue doing work on this series, and hope that we can work out an arrangement with yourself towards this purpose. If you would like to contact us, [...]
