@leocg Don't know if other adblockers have added the ad address to their block list.
I think you’re right, it's probably on a block list. It would be handy, like I say, if there were an option in Opera to permanently block these kind of ads in the same way that a user can save, share or copy an image by press-holding the screen and selecting. I don’t know if that’s doable but anyway, thanks for your feedback.
