What is the ruling on profiting from a YouTube channel through Google AdSense ads, knowing that category targeting is done without visitors knowing the content of the ad, and that most of the channel's viewers are foreigners?

Our established position is that it is permissible to promote advertisements and profit from them—whether Google ads or others—if the advertised matters are permissible, and the advertisement does not contain any forbidden elements according to Sharia (definition), such as裸露 images or music. Otherwise, it would be prohibited. If it is not possible to control and filter the advertisements, with a strong presumption that forbidden advertisements will appear, then advertising and profiting from it are not permissible. As for the fact that most viewers of the channel's content are foreigners, this has no bearing on the ruling.
