Once you are a target, or identified as a target, the random becomes not random but potentially multiple aggressive probes focusing on a single subnet or set of subnets to find and create a zombie behind the firewall.

I am not saying that hosts reject this business out of hand, but that they have to take special time, care and attention and a site might need to be promoted to a dedicated box or segregated to protect the less target worthy machines. This equals higher costs that must be charged. If this cost can't be recovered.. then the host will begin avoiding this sort of head ache.
