My appologies if this has been already stated, as I don't have time to read the entire thread. The Fusion server has one thing unique to other demo servers: no joining during race. This could potentially be boring the wreckers. On the other hand it coud simply be that the server is so popular it's hard to connect and so the wreckers don't find their way in that often. Still the no join during race could be contibuting to curbing wrecking behavior.
