Official description

Quest Bot is an opensource modern Discord Bot built for moderation, utilities and support. Prior to version 1.0.4, a user who can configure bot settings can enable logging and choose a logging channel they can read. The bot then logs deleted and edited message contents from every channel it can see, including private channels the configuring user cannot access. This issue has been patched in version 1.0.4.
