The link filter is an advanced system to help moderate links in your discord server.
This parameter allows you to set what happens when the user posts links.
action <mod points> <moderation type> [message]
What are moderation points?
If the links they posted were either blacklisted, or not whitelisted, it will add a moderation point. The whitelist point has an option to turn it on, but its disabled by default, so users will not get a mod point posting non-whitelisted links.
