Following a private channel responds with unexpected stanza

[lloydwatkin]

From lloyd.watkin@surevine.com I attempted to follow lloyd+dev4@buddycloud.org, I received the following unexpected stanza back:

<message type="headline" to="channels.surevine.com" from="channels.buddycloud.org"><x xmlns="jabber:x:data" type="form">

</message>

Unexpected because lloyd.watkin@surevine.com is (or has not been) a moderator or owner of this channel at any point.

This may be design and anyone attempting to respond that does not have permission is refused. In the java server these notifications are sent to owners and mods, if this is by design then please let me know and I'll update java server to match.

Also I don't get this stanza posted through to the account on demo.buddycloud.org :(

Here's what is seen in the demo.buddycloud.org server logs, confirmed its not sending out notifications to owner for some reason:

Ok, this is rather strange. I have now un-followed then re-followed lloyd+dev4@buddycloud.org as lloyd+dev3@buddycloud.org and I'm getting the headline message sent through to lloyd.watkin@surevine.com. This explains the above behaviour but not why I'm getting the message in the first place.

The UI shows lloyd+dev4@buddycloud.org as a moderator of their own channel.
