Ok...this is wrong what hallwagner is doing, but i have one thing to say...

I think you're the fag with no life, i mean god you came onto the forums to bitch about an exploit! WHO GIVES A SHIT ABOUT RANK! You don't know me because you haven't been around long enough, but i used to be a rank whore (like yourself) i eventually worked my way up yo 4th, and this was back when there were people on the server that had skill. People are going to find exploits no matter WHAT! The one that hallwagner is doing, has been done for years by people like james and myself.....ok let me make a list of exploits we came up with that are now banned....

Zteleing from zombies...
Moving to spectate to avoid being tagged...
Reconnecting to avoid being tagged...
Multiple now illegal spots...
One ex-admin actually scripted to make cades go fucking bonkers....

In the end it doesn't really matter! People will always find new exploits and ways to cheat, just learn to adapt or live with it! You should play this game to have fun, and if thats his idea of fun, then more power to him!
BTW this is a very good technique to utilize on several escape maps...just sayin
