Simple feature, dont happens too often but happens some times. If the players dont send any input in a 20 second window the spike will be dropped. CS:GO have this feature

Edit: Some people say this feature already exists, but is not exactly what I meant. Apparently the spike will drop if the players disconnects, but Im referring to when the player dont disconnects but leaves the computer Happened to me today, reyna had the spike in base until the end of the round, he was away from the computer
