AFK-Kicker
A Spigot plugin that automatically kicks players who are in AFK mode. You set the time limits and frequency of checking server participants' activity yourself.

Main Features
The system tracks player activity and automatically kicks those who haven't been active in the game for a long time. You can flexibly configure the plugin's operation parameters to suit your server's needs.

Permissions
