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.
