If only there were some kind of search website that, with a few key words, would find such lists for you.
Failing that, you could install the Lightbeam plug-in for Firefox and then see the shocking number of sites that get visited in addition to the websites that you want to visit. It is pretty obvious that some of them are providing the advertising. Even for those who are not, do you really need or want the site that you go to to tell other sites about you by simple links in website that force you to fetch stuff from them? I never use Facebook, will never have a Facebook account. Why do so many different websites think that they need me to get traffic from Facebook? (Even websites that show no Facebook link or logo on them often do this.)
However, I'll be nice and get you started. Put two lines in your HOSTS file that read
and see how nice things get from just that. I learned to do this over a decade ago when some "adware" that I was using not only was delivering ads from doubleclick (which I would have been fine with) but was providing a back door for doubleclick to install other stuff on my system and it was regularly crashing my system. I blocked downloads from doubleclick and my problems went away. Doubleclick has since been sold to Google, but if Google is going to enrich the weasels who were doing that I see no reason to let doubleclick traffic back into my system. (Guess where a lot of Slashdot ads come from.)
