anyone else notice that the ad blocking feature doesn't seem to work? i've been trying to block some irrelevant ads on my site but the ads keep popping up. I've had the right urls in the block list for over a week now and it doesn't seem to be working. These are not the generic vonage and mortgage ads that show up when they haven't crawled your site yet. I can understand if you can't block those default ones. anyone else seeing this?
