IIIRC you can be sneaky with things like Doubleclick
using proxies, basically they just scan through any
web page for add sized links to doubleclick and
replace them with a local - static gif image. Don't
kno much about it but i know there is such a thing.
Spam-Guard and Ad-Block (Or similar names) spring to
mind. Perhaps ad-filter. (???)
