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.

# mod_tos

A very drafty module to implement some kind of Terms of Service acceptance
tool.

Currently, this only works with clients implementing this very drafty
protocol. The result of the experiments will be an update to the
[ToS ProtoXEP](https://xmpp.org/extensions/inbox/tos.html), with the goal
of acceptance.
