I assume that everyone here knows what scanlation is, but in case you don't, let me break it down for you. Scanlation is the practice of scanning untranslated japanese pages of a manga, or "raws", translating them, and then posting them for free on the internet.
People who argue for scanlation say that it allows authors to reach readers in other countries where their manga might not be avalable. Some scanlators also claim that since they did the translation themselves, and not the publisher, the publisher has no right to accuse them of copyright infringement, since they didn't use the translation the publisher put out. They also claim that they scanlate because they love the author's work so much and want to share it with the world.
People who call scanlation illegal say it's because the scanlators are putting copyrighted things on the internet for free, damaging the author and publisher. They claim that scanlation hurts the manga buisness and could destroy it altogether. Also, most scalation sites advertise, and because the only reason people visit those sites is to look at someone else's intellectual property, it can be said that those sites are profiting from someone else's work. This is normally called stealing.
So, what do you think of the issue? Is scanlation illegal, immoral, a fuzzy gray area, or perfectly fine? I'm dying to know.
