mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

summary: 'Block remote servers via ad-hoc command'
...

Introduction
============

This module provides the *Edit Blacklist* ad-hoc command described in
[XEP-0133](http://xmpp.org/extensions/xep-0133.html#edit-blacklist) and
also performs the actual blocking of incoming and outgoing
server-to-server connections.

Using
=====

In your client, simply select the Edit Blacklist command from the list
of adhoc commands. E.g. in Pidgin, this is under *Accounts -\> (your
account)* in the menu.
