@Quaysan Let me direct you to this: https://mangadex.org/title/23569/gokushufudou-the-way-of-the-house-husband
See all those "colored" chapters? See how horrible they are? It gets worse. They did not ask for, nor do they have permission from the scanlators to do that 'coloring'. Worse yet, the scanlators asked Mangadex to take them down and Mangadex hid behind a bullshit rule that says "If it's an alteration we don't give a shit". They also have a bullshit rule that if a group requests that manga not be uploaded to Mangadex and they go dormant for a short period of time that said rules are no longer valid and Mangadex won't respect them.
They are very anti-scanlator pro-get-eyes-on-their-site-no-matter-the-cost. It's gross.
@Nick86 Batoto at least respected scanlator's wishes when it came to uploading. You know why Fallen Angels doesn't upload here anymore? https://mangadex.org/group/67
