Title
Quest Bot: Stored warn reasons can still trigger bot-powered mass mentions through `/warns`.
Summary
Quest Bot is an opensource Discord Bot. Prior to version 1.1.6, the latest release suppresses mentions when creating, unbanning, unwarning, kicking, muting, and unmuting, but stored warning reasons are still printed by /warns without mention suppression. A moderator can create a warning with @everyone or @here in the reason, then make the bot later output that reason through /warns, causing a mass ping if the bot has permission. This issue has been patched in version 1.1.6.
