🔥 New Security Features

Auto-Punishment (Automatic Punishment)

• Automatically ban-ip or execute punishment command when players attempt sensitive commands too many times
• Config: auto_punishment.threshold - maximum allowed attempts
• Supports multiple modes: ban-ip, ban, kick, firewall, or custom command
• Firewall script: Execute system commands (iptables/ufw) to block IP at network level
• Configurable sensitive commands list: sensitive_commands

IP-Limit (Multi-account Detection)

• Track number of accounts connecting from the same IP
• Auto-flag and punish if exceeding max_accounts within time window
• Default: 3 accounts / 5 minutes
• Integrates with Auto-Punishment to automatically block suspicious IPs

Shadow Ban / Fake Success (Deceptive)

• Instead of showing "no permission", display fake success messages
• Attackers think they succeeded but nothing actually happens
• Buys time for admin to investigate and handle attackers
• Fake messages for commands: clear, kill, ban, gamemode, tp, effect, give

Anti-Spam Console Log

• Blocked commands no longer appear in console log
• Only logged to audit.log to prevent server console spam
