In before the ban request :P

My brother came to me earlier discussing a potential map exploit he had discovered so i invited him to show me how it worked and this was done on your server as it actually had players done, i'll be reposting this on the steam forum as a map bug anyway so i hope we don't get banned, here is the vid so you can spot people doing it
