how do you guys target users?

Seems like only real targetting that's possible is male or female.

or pages people like. which is cool. but the location + age becomes a problem.

Good luck getting people to tell you. Targeting people is the key to all direct marketing efforts. What you need to do is track the people you promote and what type of offers you send. Create categories for your offers such as Fishing, Football, XBOX, etc. Then if you can track the people you are promoting and which offers they respond to then you can keep promoting them similar offers of the same category. It can be done.

I start a new account off by adding 5 people from the area I want people added in and leave it run for 2 or 3 weeks adding 10 friend suggestions every day, at the end of the 3 weeks i go into the account and manually delete anyone not living in that area and then turn it on for a month or 2, at least 50% of the people in any account i do that on are from the place in question. i dont see why anyone would hide such info from you, its not like your going to mess with my system knowing this.

Hope this helps someone

yeah I'm figuring out how to get the bot made.
