Doubleclick domains show up in a lot of hams.
Have you seen these domains in URLs mentioned in e-mail ?
0mm.com 123 / 94 in *.net-abuse.* (incl. / excl. nanas), last 2002. rather old, but not a "white hat". 2clk.net 93 / 25, last Aug 14 2004, zero sightings after removing the dubious launch.2clk.net addresses
businesslink.net sightings in some very old spam (1999).
I'm not very interested in ancient spam history, but after this short reality check this isn't a clean list of known white hats.
You just don't have the time and Gigabytes to white list all ex-spamvertized domains without new sighting for more than two years. The purpose of your white list is IMNSHO to catch erroneous SURBL listings. It's not a collection of reformed spammers or old domains. At least for c/n/o the whois data allows to determine the age of domains.
And if they spammed before 2003, who knows what they are planning for 2005 ? Bye, Frank
