Those folks who don't see the ad, my best guess is that you're subscribed to a Filter List that has already caught that domain.
I was getting the ad, and I added this filter to remove it:
##[src*="hostingkartinok.com"]
However that just hides image that comes from the domain, it doesn't block the call. I didn't have time to figure out the precise AdBlock filter syntax to block calls to the domain.
So it seems at some point i blocked the whole ad frame for ef.
