Is it permissible to earn a living from a blog where you claim to be a girl to attract foreigners and earn money from their views and clicks on ads?

What you are doing by impersonating another person is a form of lying and deception, and it is forbidden for you to do so; you must desist from it. As for earning money through advertisements, it depends on their content: if they are permissible, there is no harm in earning from them. But if they are forbidden, then the earnings are forbidden. It is not permissible to subscribe to the website if you cannot control the displayed advertisements.
