All publicly-listed ad delivery systems like Meta do in fact need to deal with high-income countries.

They can't afford to and will never strike off 100m Brits and Aussies, and that number will only rise with more high-income countries making regulation.

imgur blocking the UK is not due to ID verification, but because they refused to stop making money off childrens data.

The reason is irrelevant. The point is websites don’t need to deal with <insert country>.
