Comcast is known to emit lots of abuse -- are you blocking all their
networks today?

After thinking it over: I partly-to-mostly agree.  In principal, yes.
In practice, however, [some] negligent network operators have built
such long and pervasive track records of large-scale abuse that their
allocations can be classified into two categories:

	1. Those that have emitted lots of abuse.
	2. Those that are going to emit lots of abuse.

In such cases, I'm not inclined to wait for (2) to become reality.
