⬇ Download on SpigotKeep your server safe and friendly! Gatekeeper requires all new players to explicitly accept your server's terms and conditions before they can play. Players who do not accept cannot interact with the server until they do. Admins can also manually block disruptive players at any time. Blocked players cannot move, chat, build, or take damage, and are presented with a detailed GUI explaining their block status. All texts and rules are fully customizable in the configuration settings.
Easy-to-use commands are included for blocking, unblocking, and checking block info. This makes Gatekeeper perfect for whitelisted, 18+, and community-focused servers.
