Just because you get a lot of clicks from Asia, it doesn't mean that they have click farms there. Don't know if you've been to Southeast Asia, but there are a lot of people and most of them use Facebook. If they see the ad they might click it because they're interested, even though they cannot buy the product because they're in the wrong country. Still doesn't mean that FB fakes clicks, it just means they target them badly.

And even if the accounts are fake, they were likely created to sell followers/likes, not to click ads. Clicking on things just shows activity.

I'm sorry I can't really get into a discussion with you (or anyone else) without getting into serious NDA violations.
