It will trigger the ban in L4D2 if a player is using the mounted machine gun. My server is not modified.

It happens on the second map of No Mercy (Subway). I do not know about other mounted machine gun, but two players including myself were ban while was using the machine gun.

I was finally able to reproduce this by lagging my connection to the server. The method used to hook these weapons along with L4D2's low tickrate gave the unexpected results.

It will be fixed for the next release, thanks.
