Handle Deleted Content in a Community Message
Deleted content may continue to show up in your Community feeds. This happens when your customer deletes their message on the native platform/platform of origin (such as Facebook or LinkedIn). Typically, there is no reliable tool to detect all the content that was deleted on the original platform.
However, when you try to respond to such content, the message will be marked as Deleted
(see Understand the Actions and Buttons of a Community Message).
