It would be great to have mod_firewall work on MUCs, and provide additional functionality there. First, I have no idea whether mod_firewall would work on a MUC domain at all, and with which side effects. Second, the following (native) features would be great: - tracking of spammer occupant JIDs in a global (not per-MUC) list message treatment: - rejection of MUC messages that violate firewall rules - silent dropping of MUC messages that violate firewall rules - shadow-ban: only reflect messages to the sender, but to nobody else occupant treatment: - kick occupant - ban occupant - add occupant to spammer list
