Scanlation groups tend to have one or more preferred reader websites/apps. Most groups will upload a file to their own website and also send an upload request to their service of choice, which for yuri groups is usually Dynasty.
Once a work has been submitted to a reader, other website/app managers will acquire the files from there and upload it into their own services. This is what MangaFox does.
MangaFox is kind of an arse really, because they do not respect scanlators at all. So, for example, a few scanlators request websites to wait some time before uploading their releases (like one or two days), because they want people to get the release from their website first. In the past we've seen MangaFox circumvent this by uploading stuff to MangaHere, one of their parallel services. Other times MangaFox simply doesn't care.
This is why sometimes you see messages like "Don't read this anywhere other than Batoto" show up in the middle of manga. Scanlators are used to their requests being ignored by reader websites. Also, we don't get any compensation for our work at all, nor does the original author, so it feels unfair that a website gets to profit over something you did for free.
