Edit: Btw I deliberately posted this in the "complaint department" rather than "ban request", but seems he got banned anyway. I also wrote "almost" blocking, it was still possible to get past duck jumping over the dispenser. Later he built a teleporter which could also be used. Here's a demo, starts around 70 minutes in: http://hltv.esclan.net/zip/battlezone/HLTV-1910271429-2fort.dem.zip
