[Dxspider-support] Weekend data

I have a direct connection to K1TTT and he was the primary source of the 
copy attack traffic. It appears that AR Cluster does not have the same 
resource issues when used just as a "bounce node" (A node that only 
allows connections to other nodes - no users). I would see a genuine 
spot come in from somewhere and then, within seconds, the copy attacks.

Now it's not K1TTT that is responsible, his node is just the vehicle.
