You must be getting downvoted by people who have never run an ad-supported web site.

When I used to do that, North American traffic got ads 100% of the time. European traffic might get ads 5% of the time. Otherwise, there were few advertisers that cared.

However, this was back before Google AdSense upended the industry, and you could still make a living showing one static ad per page.

It's afternoon in Europe, and folks generally don't like to be reminded of the fact that their market is decreasing in global relevance.

In this case, ads are even a product people actively want to avoid, but it's still unsettling to be undesirable. Imagine banning smoking and then getting upset that Philip Morris doesn't want to sell to you anymore.
