I have noticed that lately when I boost a post on Facebook, using the US as my location, and refining my audience by interest or job title I'm pretty picky here , I'm still getting a lot of likes and clicks outside these parameters.
My current ad has likes from India and Mexico.
All of them based on their profile don't really fit the right interest molecular biology research instruments for this ad .
I've based my audience on those interested in molecular biology, specific research applications, job titles such as laboratory manager, research assistant or principal investigators.
So far I'm getting restaurant managers, retail managers, and unnamed people from outside the US.
I know facebook has had issues with click farms, but this is insane.
