So you're a rights holder for a manga we're scanlating? More than likely you're Dark Horse Comic, or Yen Press, or Vertical... or one of a number.
If you've got some way to prove you're a rights holder of a manga we work on and you disapprove of it's scanlation, send us an email at firstname.lastname@example.org. We can't keep track of what's being licensed... we just don't have the time to track that.
If you contact us and prove you are a rights holder, we will remove all chapters from our downloads page. We will also ensure that we delete any chapters we have uploaded to bato.to. Unfortunately, nothing we can do about other aggregators and reader sites. We do this in order to promote the official releases.
