1) I've been receiving a lot more spam (addressed
to the username I subscribed to this list) recently.
Have others seen the same activity?

2) Heck, there's been a sharp increase in spam
in the last month or two, too.  It seems to be
originating from a much more widely distributed
set of hosts.  Have others seen this also?
Explanations?  Why aren't the blacklists keeping
up--or are they, and is the volume that much greater?
I'm using CBL, SBL, and CN-KR, among others.

Thanks
