Spamhaus provides a snapshot of its PBL activity, including graphics of activity by net block for particular providers. The graphics show activity by /24 blocks in "hot" colors against a light blue baseline, which enables you to get a glimpse of the distribution of problems in particular providers' address spaces.

Turk Telecom is held up as a bad example (apparently, Turkish law gets in the way of prompt enforcement), while France Telecom and (drum roll) Comcast are extremely clean. The Comcast example is particularly encouraging.

Yeah, a bit like 'the return of the prodigal son' sense of elation considering they were perennial tops of 'the hall of shame' until just a few years ago.
Sc's individual graphics on /24s:
