Do what some people do to block doubleclick - make your server
authoritative for the doubleclick.com/net zones, and don't enter any A
records. All the lookups in those domains will return NXDOMAIN against 
your server(s).

There's other ways, but this is the easiest to explain (and implement)
that I can think of offhand.
