Kicked for Inactivity is an AFK prevention in Modern Warfare 3 to ensure active participation and balanced teams. However, it appears that the measurements for detecting inactivity have become stricter in the MW3 multiplayer, resulting in players being kicked out after relatively short periods of camping, sniping, or crouching. This guide aims to shed light on the causes of this issue, clarify whether it is a bug or intentional design, and provide best practices to avoid being kicked for inactivity.
