You are the one being simplistic.

Please go to http://dsbl.org and read about it.

For some IPs, yes, I can, with 99.95% of confidence.

You have to be aware that these IPs are not the ones that people normally
use to deliver their email (i.e the IP of your ISP's SMTP server).

My advice has not changed: Please go to http://dsbl.org and read about it.

I know for sure that AOL fights spam. They even sue some spammers from
time to time. Go to their web site. It's very interesting.

You are missing the point because you don't know how DSBL works.
Please go to http://dsbl.org and read about it.

AOL's outgoing SMTP servers are not open relays.

If debian-admin eventually gives us the opportunity to block messages
from the DSBL on a per-user basis, it's nearly impossible that a
message you send me from AOL to my @debian.org address is blocked by
master, unless AOL makes a big configuration mistake in their SMTP
servers, but they would surely fix this immediately, since many people
blocks messages coming from open relays as well.
