What xoxo AntiCheat is
xoxo AntiCheat is a free, open-source server plugin for Paper, Bukkit, and Spigot Minecraft servers. It loads 18 checks across packet, movement, combat, and block categories. When checks detect violations, the plugin can flag them and rubberband the player, blocking movement, camera rotation, and inventory actions. If several violations arrive in one tick, they are spread across later ticks, with at most one flag per player in each tick. A velocity simulation models player physics to help distinguish legitimate movement and reduce false positives. Administrators can set a flag threshold for automatic bans and provide readable ban messages. The `/xoxo` command supports exception-list management and lets administrators view a player's violations. To install it, place the `.jar` file in the server's `plugins/` folder; ban history is stored locally. Listed compatibility covers Paper, Bukkit, and Spigot versions from 1.20.5 through 1.21.11, with some versions marked beta. Versions 26.1 and 26.1.2 are planned. The project uses the MIT license and invites issues and pull requests.
