1. /antiraid <on|off>
   Automatically detects and manages raid attempts by:
   Temporarily muting all new members.
   Limiting the join rate (e.g., X users per minute).
   Notifying admins of suspicious activity.

2. /dynamiclock
   Locks a feature (e.g., stickers, links) for a set duration and auto-unlocks it. Example:
   /dynamiclock links 30m temporarily disables links for 30 minutes.

3. /shadowban [reason]
   Silently bans a user, allowing them to stay in the group but preventing others from seeing their messages. Useful for stealth moderation.

4. /autokick
   Automatically kicks members based on specific criteria, such as:
   Inactivity: /autokick inactive 30d (members inactive for 30 days).
   Join-and-leave behavior: /autokick rejoiners.

5. /contentfilter <on|off>
   Advanced filtering for messages with specific types of content:

/contentfilter links on blocks all shared links.
/contentfilter keywords on scam, fake blocks messages containing flagged keywords.
