For the last few years, I've used the PithHelmet ad filter program on Safari to weed out DoubleClick, Federated Media and more. But as Apple introduced Safari 3.0 beta on Mac and Windows, PithHelmet hasn't kept up. With the ads back, I downloaded SafariBlock and have been starting over, right clicking on all ads I see, and adding a * asterisk for wildcards so I won't see anything like them again. But if I right click on Flash ads, that option isn't there. I also don't have any way to hide Google's text-based AdSense advertising, which pollutes many blogs and media sites.
I expect there to be a continued war of development between the advertising community and those of us consumers who want to decide for ourselves, without pervasive marketing. Today, Flash and AdSense are the filters' achilles heel, and are driving me a tad nutty. I wonder how long I have to wait until the filters catch up...
