Anonymous AO3 Collections

The Archive of Our Own allows users to create and maintain "collections" within the archive, often but not always for moderating challenges. The collections feature includes an Anonymous setting, which hides the creators' names on every member work. This setting may have been intended for a few types of challenges (anon memes and exchanges like Yuletide that have an anonymous period before authors are revealed), but users started setting up permanent "Anonymous" collections for reasons of their own.
==Use in challenges==
Many gift exchanges have an anonymous period after gifts are revealed and before creators are revealed. Anonymity was built into AO3's collections functionality from the beginningSee the September 8, 2008 comment listing core collection requirements: . Accessed 11 August 2022., with Yuletide, a massive gift exchange with a one-week anonymous period, as the first test case going live in 2009., 28 December 2022. Yuletide is the oldest collection on the archive, created on December 17, 2009.. Accessed 11 August 2022.
In July 2011, prompt memes were added as a new collection type., 11 July 2011. Both prompts and fills could be posted anonymously, depending on what settings the collection maintainer chose.
==The first "Anonymous" collection== 
The first permanent anonymous collection not associated with a challenge was called simply Anonymous, and it was created on November 14, 2010 by a user called "nonnie". Any AO3 user may use the collection to dissassociate a work from their username. If a work is added to the collection, the author field will just display "Anonymous" to readers. However, the original author will maintain full control over the work, including receiving kudos and comments and being able to edit the work. 
"Anonymous" is a popular collection, with 149,753 works in 8309 fandoms as of 2024. (Accessed 8 December 2024.)
==More anonymous collections==
The "Anonymous" collection was followed by several other similar collections, though none became as popular as the first. Some of the larger ones:

*created 2013-06-02 anon_fic (1991)
*created 2016-02-13 anon (14026)

==Privacy issues==
Adding one's work to an anonymous collection doesn't grant complete anonymity. The collection owner can see the creators' identities. The collection owner is also publicly displayed on the collection profile, so users can't create anonymous collections for their own works to avoid revealing themselves to a third party unless they create a separate throwaway account for it. Finally, the collection owner can easily de-anonymize the entire collection by unchecking a box at any time.
In November 2019 AO3 coders fixed a bug that had previously allowed collection owners to add works to their own collections that were in anonymous collections., Resolved November 6, 2019., 21 December 2019. Before the bug fix, a user could reveal the identity of the creator of an anonymous work by exploiting this bug. It appears that the bug was discovered and exploited the previous month by people on fail_fandomanon who were successful in uncovering the identity of the author of an unrequested racekink fic in the Darkest Night exchange., anonymous comment, fail_fandomanon, 2021-06-17., anonymous thread, fail_fandomanon, 2019-10-04.
In 2021 shinelikethunder commented on the dangerous level of trust people had placed in anon collections:
