2.4 If a group has had no releases on MangaDex or any websites affiliated with that group for a period of 6 months, the group will be considered inactive.
2.4.1 It is possible to request a removal of inactive groups' upload restrictions.
These two rules are placeholders, as they are currently working to implement an inactivity feature that will automatically email the group after a period of time if they do not respond to on-site PMs.
The updated rules for when the previously explained feature is added:
2.4 A group that has had no new releases on MangaDex or any websites affiliated with that group for a period of 6 months is eligible by the request of any user to become marked as inactive. 2.4.1 Upon receiving an inactivation request, MangaDex staff will attempt to contact and notify the group. 2.4.1.1 It is possible for the notified group to request becoming exempt from being marked as inactive [for a period of up to 2 months]. 2.4.1.2 If the group is not exempted, it will be marked as inactive after 2 weeks from the initial notification. 2.4.2 An inactive group will have all of its upload restrictions lifted and its leader and members will no longer have automatic editing and deleting permissions to the chapters associated with the group. 2.4.3 Should the group resume releasing new content, it will no longer be considered inactive and the normal permissions will be restored.
