To cut down on abuse, we have just rolled out some changes to co-creating works, chapters, and series on the Archive. Until now, it was possible for any user to list you as a co-creator without your approval. We've added creator invitations to ensure you won't be listed as a co-creator until you accept the invitation. Additionally, we've added a preference that requires you to opt in before other users can invite you to become a co-creator.
Nothing will change about existing co-created items: all creators will still be able to edit the work, chapter, or series even if they do not enable the preference. Before you can be invited as a new co-creator, however, you will need to enable the "Allow others to invite me to be a co-creator" option on your Preferences page. (Where can I find my Preferences?)
Turning the preference off will not remove you from any co-created items, nor will it prevent any of the item's existing co-creators from making changes. You can turn the preference on and off as many times as you like. Turning the preference off will not delete any co-creator invitations -- you'll still be able to find them by following the "Creator Invitations" link on your Dashboard when you turn the preference back on.
If you need to add a co-creator who does not have the preference enabled and who you are unable to contact, you can use the Notes field to provide proper credit.
We're sorry we weren't able to announce this change ahead of time like we usually do, but adding co-creators who did not wish to be associated with a work was becoming an increasingly common abuse and spam tactic, and we didn't want to cause a spike in these incidents by publicizing it before this fix was live. We hope the changes provide relief for users who have been targeted and help everyone feel more in control of their experience on the Archive.
