nah, those watermarks are just fine, the only ones complaining are the snipers who depend on a clear image to work with/steal/claim. Keep those watermarks if you want, because it is fine. It does not obscure the story or image in anyway, unless you want to snipe it.
Also, thank you for the scanlation.
What? The scanlators themselves said they made a mistake which makes sense, aggressive watermarking make people drop series. The way they normally do it accomplishes the goal and isn't aggressive. And you really think the groups that steal are a big deal when the scanlators post to mangadex?
Also in most cases snipers don't steal other peoples translations/work, they steal series (usually from slow scanlators) by posting new chapters before the main group doing them do (usually with garbage mtl and poor quality everything). I have no clue where you got that snipers are cleaning watermarks and stealing translations. There are sites and groups that do that but they aren't snipers, they're just asswads and usually low quality with obviously garbage sites.
And what do those groups get out of it? Maybe a couple people visit the site, see it's crap and leave. Even more so with series dual hosted on mangadex where a decent number of people would find it first and then find the real scanlators page through it. Mangadex usually would pop up high on web searches too from my experience so no clue how you'd end up on sites of those that go through the effort to steal fan translations.
