Since I'm one of the few people who has this data, I can tell you that 
actual 'number' is not as usefull as it may seem. There are different
RBLs with different focus and point of view and while some list individual
ips and live for a few days, others list ip blocks (and sometimes entire 
allocated block) can exist for months and years and are result of manual 
research. The first one causes a lot highier number in ASN RBL listings 
but underscores significance of the block listings.
