Currently the only possibility for managing links is to disable them all together. This replaces them with '***' in chat for everyone but the sender. Add an alternative to make AutoModerator hold all links for review instead so mods can allow them on a case to case basis. If no mod is there the result would be the same, no links in chat.

Allow another wildcard besides * to match just a single character. The catch-all * has a tendency to over-aggressively block desirable messages when used to block a short triggering term

Rather than removing emotes, create a chat filter that checks
emote tags. When approving emotes, apply rating tag to emotes that could be considered "sexual/explicit", these would be filtered out in channels that haven't enabled the 18+ notification.
