In addition to NetPositive’s built-in filtering capabilities, there’s another technique you can use to block ads originating from most of the major web advertising services, and that is browser independent (i.e. will work with Opera, BeZilla, and lynx as well).
Visit this page and copy the contents to the clipboard. Then open up /boot/beos/etc/hosts and past the contents into the end of the file. Restart networking. This will effectively point all major ad hosts back to localhost, thereby causing them to fail.
