Duplicate local copies created from remote followed Socialhome profile posts
When following another Socialhome profile in a follow that was initiated over ActivityPub, all posts from the profile will be duplicated locally into two variants IF also subscribing to the relay system:
- one received over activitypub
- one received from the diaspora relay system
The solution is to add the ActivityPub ID to the diaspora payloads and the Diaspora GUID to the activitypub payloads so that we can recognize another local copy.
