Good day. Previously, we have discussed about comments node over PEP. https://xmpp.org/extensions/xep-0277.html#comment_add

Note: A comments node SHOULD be located at a generic publish-subscribe node that is not attached to a user's IM account, but MAY be located at a personal eventing (PEP) node.

While PEP nodes are only accessible to the account owner, it is desired to have people to post items to PEP comments node. I would advise to utilize XLink as a mean of references to moderators and by that, it would be possible to create a uniform comment moderation mechanism for posting comments of Atom Over XMPP (XEP-0277 and XEP-0472). https://www.w3.org/TR/xlink11/ Kind regards, Schimon
