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).
