ads getting through piblocker & blacklist.. about pi-hole

this is the source from the site..

The image displayed is hosted on glocdn.investing.com not on pubads.g.doubleclick.net (which is where the link directs you to if you follow it).

I just ran cat /etc/pihole/gravity.list | grep investing.com and didn't find investing.com as part of a black holed domain. This would explain why you're seeing the image as @korhadris mentioned. If you click on it though, it should be blocked.

pi@dns ~ $ cat /etc/pihole/gravity.list | grep pubads.g.doubleclick.net
192.168.0.3 pubads.g.doubleclick.net
192.168.0.3 securepubads.g.doubleclick.net

Where 192.168.0.3 is the address of my Pi (yours will be different. Probably 192.168.1.176)

Yeah that was my thought as well.. But how does an addin like Adblock know to block the same ad?
Doesn't it use the same tech?

[Symbiot78]

I see they use css injecting as well..
I guess I'm just looking for the whole package

Yeah adblock looks for certain advertisements using the <div> on the page and blocks it that way. The ads are still loaded, but adblock hides it.

Pi-hole blocks the ad from even loading (by using DNS) - but if the ad is on a trusted server (like investing.com), then there's not much you could do.

@poblabs said it well. The Pi-hole cuts ads off at the source for an entire domain or subdomain, where as ABP uses CSS-injection. Each has their own strengths/weaknesses. As is true of many things in technology, a layered approach usually works best. Personally, I use the Pi-hole for blocking the majority of ads and saving bandwidth, and then I supplement it with ABP for cases like this.

Since it's not really an issue with the functionality of the Pi-hole itself, rather the specific site/ad combo, I will close this issue.
