What is a routeblock?
A routeblock is a range-ban preformed on a location to disable access from the 'blacklisted' players. Being routeblocked disables your ability to join the server causing nothing but a ban message to pop-up. The routeblock usually won't hit any innocent bystanders, unless the IP/ISP belongs to a very high population area in that location.
