I've had good luck with Facebook ads. I think the targeting is key. If you target people who are already familiar with your brand, it helps a lot. You can target, for example people who already "Like" your page. And you can target their friends as well. Facebook also has a feature that lets you serve ads to people by their e-mail address.
If you stick with those, you're pretty much guaranteed to be targeting real people, and not bots or fraudsters.
Also, learn to use the Facebook Power Editor, as you get a lot more control over how your posts appear, how your ads work, etc.
