TOPIC: Player griefing in CB server 13

I was just finished a CB game on server 13. At one point a player named Ubimixicit was trying to grief me with trains. He was going to destroy my Goods trucks(at least that was his plan). Luckily I was paying attention to this part of the map and blocked him off. Then at one point he managed to get a train running and I quickly build a bridge over his rails. Multiple admin calls without response unfortunately but I managed to take a screenshot of it.
