So back to my ACL's I go!

This is one of the most likely things to happen.  DNS RBLs are effective.
Otherwise spammers wouldn't be targeting them for abuse.

What evidence is there that spammers are the ones doing the DDoS?

        There is likely some conjecture here, but aside from the DNS RBLs
that cause collateral damage (ie: blacklisting large chunks
of address space to cause behaviour change) who has something to gain
from these dnsbl's going down?

Isn't that collateral damage issue enough to have angered hundreds of ISPs
& end users to the point of not necessarily organizing a DDoS, but ignoring
it?  I think it is far _more_ likely that the DDoS came from the innocent
victims fighting back rather than the spammers.
