I don't run any kind of blocker service. And of late, am rarely bothered. There was that Patak's ad, which I supplied screen shots of, and now it seems gone. Every so often I hear a blip of sound, but it is immediately silenced. Again, it hasn't been a bother for me on any device ... phone, tablet, desktop ... for a while now ... Patak ad aside. I'm on Apple products with Firefox on my desktop and Safari on both phone and iPad.
