Recommendation: Monitor — no exploitation signal at the moment.

Quest Bot is an opensource Discord Bot. Prior to version 1.1.6, the automod add command trims user input but does not reject an empty result. Adding a rule containing only whitespace stores an empty word. The message listener later checks content.includes(""), which is always true, causing the bot to delete every non-bot guild message. This issue has been patched in version 1.1.6.
