Designed for Small Public SMPs

AntiAltGuard was built with small public SMPs in mind—where fairness matters most.
It prevents players from abusing lifesteal mechanics by creating alt accounts to farm infinite hearts. With IP tracking, health-based restrictions, and smart monitoring, your server stays balanced and competitive.

Commands

• /antialtguard ignore : Allows a player to create alt accounts (adds to ignore list).
• /antialtguard moniter : Restricts a previously ignored player from making alt accounts.
• /ipunlink : Unlinks a player’s IP so they can shift accounts. Requires 10 hearts, making it lifesteal-friendly.

Configuration

• Enter your email-id to turn on anti vpn.

Why Use AntiAltGuard?

Alt accounts and VPNs can bypass bans, exploit lifesteal mechanics, and disrupt fair play. AntiAltGuard gives you the tools to fight back—without bloating your server or overwhelming your staff.
