-# Activities for following user actor **(EXPERIMENT)**
+# Activities for following user actor (removed)
 
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/127023) in GitLab 16.5 [with two flags](../../../administration/feature_flags.md) named `activity_pub` and `activity_pub_project`. Disabled by default. This feature is an [Experiment](../../../policy/experiment-beta-support.md).
-
-FLAG:
-On self-managed GitLab, by default this feature is not available. To make it available,
-an administrator can [enable the feature flags](../../../administration/feature_flags.md)
-named `activity_pub` and `activity_pub_project`.
-On GitLab.com, this feature is not available.
-The feature is not ready for production use.
-
-This feature requires two feature flags:
-
-- `activity_pub`: Enables or disables all ActivityPub-related features.
-- `activity_pub_project`: Enables and disable ActivityPub features specific to
-  projects. Requires the `activity_pub` flag to also be enabled.
-
-## Profile
-
-This activity is the first resource ActivityPub has in mind:
-
-```javascript
-{
-  "@context": "https://www.w3.org/ns/activitystreams",
-  "id": USER_PROFILE_URL,
-  "type": "Person",
-  "name": USER_NAME,
-  "url": USER_PROFILE_URL,
-  "outbox": USER_OUTBOX_URL,
-  "inbox": null,
-}
-```
-
-## Outbox
-
-The user actor is special because it can be linked to all events happening on the platform.
-It's a join of events on other resources:
-
-- All release activities.
-- All project activities.
-- All group activities.
+This feature was documented [before it was implemented](https://gitlab.com/gitlab-org/gitlab/-/issues/426372).
+See [Implement an ActivityPub actor](index.md) instead.
