You can enter the filter into iCab's Settings/Edit Filters/Advertising/Create New Filter. Keep the setting to Blocked (default) and either reload the page or, maybe better, exit iCab and re-enter. The string I gave above is still working for me this morning, it's possible that in Europe or in different parts of the country a different URL is in the ad (press and hold the ad to copy the URL and use wildcards to difine the string). I noticed the ad last night when Marie and others began discussing it. It should only take a second to block it. Hope this is a little more precise.
