Yes, I know this, but the SBL is a combination of four classes of
"offender", as shown here:


Only the first criteria is "Spammers sending bulk email verified to be
unsolicited (spam) directly from static IPs under the spammer's

Ideally you want to be able to block all XBL hosts and the first type of
SBL host. There's no reason, other than political retribution against
spammers, to block the other three classes. They are not spam sources,
and so you don't have to block them to eliminate your spam. In fact,
blocking them won't reduce your spam load by a single message.
