In other words, it's okay for an ISP to scan systems so long as they receive
a connection from the system without spam on hand. However, it is not okay
for a 3rd party to do the same scan, despite the fact that using a 3rd party
limits the number of scans performed by aggregating the results. Considering
how much we complain about route aggregation, I'd think scan aggregation
would have a higher interest. FireDaemon is becoming pretty popular after
all.
