I'm not really sure about this, but it's VERY suspicious. I mean really. Allow me to explain what happened:
I saw his server and decided to see what it looked like. Only a few seconds after I joined I was banned. Suddenly I became suspicious. I started my own server and loaded up my D-day build. It's brick count was 300 away from mine, but that got me thinking. I removed all the junk I had behind the build (which I never removed due to laziness) and found the new brick count to be close. VERY CLOSE. It was actually within about 30 bricks. I decided to join his server using my other ID. I was not banned, and actually stayed for a while. However, I never spawned because he closed the server. I am amost sure he took my build, this is just too weird. Anyway, here's his name and ID:
Darknight (ID: 3545)
