Let's be clear: Mangahere doesn't translate anything. Legit or otherwise. All they do is host other people's translations. On top of that they (as well as Mangafox and many similar sites) are for profit, making money off of ads. And to be sure, 0% of that money goes to the original creators or even to the fan translators, it's all for the people running the website.
If that wasn't enough then also note that they frequently lower the image quality from what the original scanlators put out to reduce bandwidth costs (and maximize their profits), and they've even cut credit pages so you can't tell who actually did the translation. Basically, they're total scum. Believe me, I've actually done scanlation stuff before and everyone in that community absolutely hates Mangafox, Mangahere, and their ilk.
If you're going to go with scanlations (and of course I would always suggest legitimate sources when they're available) then batoto.net is a much better choice. Or even better just go to the scanlators' sites directly.
