is basically fiddling with your rates (updaterate, cmdrate, etc) to limit the connection between your client and the server, which causes your hitboxes to trail and makes you very hard to hit. While I don't believe VAC can catch you doing it (since you're using in-game commands to do so), most server admins will see it and ban you for doing it.
