I can't argue with your personal experience, but I can say that from what I have seen, you can target around click farms. Obviously if you are in the countries that have bulk amounts of clickfarms, you shouldn't shut those countries off, I am in the USA, so for me, it is best to turn them off. As for the 'truth' about Facebook not doing enough, that is up to the person spending the money. In my experience using ads on Facebook I have the tools I need, unfortunately that may not be true for others.
Thank you for reading and your comments, I really appreciate them.
