     • Detects and flags posts containing explicit language using an extensive list of profane words.
     • Sends a private message to the user notifying them of the inappropriate content and flags the post for moderators.
   • Spam Detection:
     • Flags posts containing more than five links as potential spam.
     • Sends a private message to the user and flags the post for moderators.

2. User Engagement:

   • Daily/Weekly Summary:
     • Automatically generates and posts a summary of the top 5 most viewed discussions.
     • Keeps the community informed and engaged with popular topics.
   • Welcome Message for New Users:
     • Sends a personalized welcome message to new users upon account creation, encouraging them to participate and seek help if needed.

3. Custom Commands:

   • Advanced Help Command:
     • Adds a custom command @system help advanced to provide advanced resources and help links to users.
     • Responds with a detailed list of useful forum resources when triggered.

Benefits:

• Improved Moderation: Helps maintain a respectful and spam-free community by automatically flagging inappropriate content.
