Just right click the ad, get the server's address, and paste it into the Blacklist.

Of course if web sites are really worried about loss of ad$ and if the ad industry can't sue the ad-blocking software companies, they always can embed the ads in their own websites and don't serve them from outside ad serving companies. If the ads are totally integrated and served from the web sites own servers, blocking the ads gets to be very difficult, although not impossible.
TV shows are to a small degree starting to do this. Instead of separate commercials, some are starting to put crawls across the actual show content. And they can use product placement within the actual story. Like some shows always use Ford cars instead of GM or Toyota.
Ultimately the advertisers will find a way. It just takes their current ways to stop working to get them to change.
