The top of economist.com has a 250px high `adComponent_adcontainer__eooQr` div.
My Pihole blocks its content, but I have a guess as to what it is.
They seem to think they have advertisers. https://myaccount.economist.com/s/article/How-do-I-advertise...
The ads they accept are basically just classifieds for high-level positions in NGOs.
I turned off anblocking and see zero ads on the site.
