Here you can configure Prosody <a href="https://modules.prosody.im/mod_firewall" target="_blank">mod_firewall</a> module. You can create multiple configuration files bellow, and change their order. Don't hesitate to share your configurations with the community (for example by adding some examples in the plugin documentation).
You can enable an "Emojy only mode" in your chatrooms. When this mode is enabled, participants can only send emojis (standard, or channel custom emojis). Moderators are not affected by this limitation.
This mode can be usefull for example: <ul> <li>To avoid spam or offensive message when you are not here to moderate.</li> <li>When there are too many speaking participants, and you can't no more moderate correctly.</li> </ul>
To enable or disable this mode, you can use the room configuration form. If you want to enable it for all your chatrooms at once, you can use the button bellow.
By enabling this option, the moderation bot will automatically delete messages containing more than X special characters. Special characters are those that don't fit into one of these categories: letters, numbers, punctuation symbols, currency symbols, emojis.
