this is kind of a long shot but I'm friends with an artist who doesn't want her work included on here
is there anything she can do about that?
I guess that depends what exactly your friend wants taken down.
If it's the whole title, then that's a pretty clear no unless it's bad data or some special case (ask staff if you think it is)
If it's the chapters (the content of the manga/comic), then your friend has to contact staff (a moderator or admin) directly here on the forum, on
Discord or at
support@mangadex.org for further conversation.
But please remember that mangadex only hosts fan translations without any ads (if it's on MangaDex then
it will be on other ad-plagued sites anyways). Any official release of any work is forbidden (as long as it's commercially available) and will be deleted after reporting it to staff.
