Single Character Wildcard
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
Use longer triggering terms before the wildcard. Or allow the term for now and click the "block term" button when someone eventually uses it in chat. Then it will start blocking the term properly without blocking regular "desirable" messages. Auto-mod is not over-aggressive. It is a bot that only blocks the inputs you give it. A little moderation of your own will sculpt the blocked words list more effectively.
In the meantime, i have a bot with no dependencies that can use ECMA script regex.
