That's rich, given the enormous quantity of spam sourced from Comcast's
network over the last decade. (And yes, it's ongoing: 162 unique sources
in the last hour noted at one small observation point.)
Spam is irrelevant. In this context, abuse = sending large amounts of
data to Comcast customers (at their request) without paying at the Comcast
toll booth.
Now I realize that SMTP abuse isn't exactly the most bandwidth-chewing
problem. However, it's a surface indicator of underlying security issues,
which in this particular case can be summarized as "one heck of a lot
of zombies". Given that those systems are known-hostile and under the
control of adversaries, it's certain that they're doing all kinds of
other things that chew up a lot more bandwidth than the spam does.
It might even "improve" their ratios if they stopped those zombies from
sendig spam, participating in DDoS's, etc. After all, that's outgoing
traffic, and the less they send, the worse the ratio gets for networks
sending data to Comcast.
