Unfortunately, if I run an ad targeting 18-24 year old males in New York City, and my ad manages to collect IP addresses, I have effectively purchased information about anyone who sees my ad.

It's certainly not a complete profile, and may have ranges of categorizations (i.e. 18-24 years old) BUT as an advertiser, I probably wouldn't need or want data more specific than that anyway.

Unfortunately you can’t collect IP addrssses from people who saw your ad though, because FB doesn’t let you :)

You can of course though collect them if people actually click on them and come to your website! This is also the case for non targeted ads mind you as it’s simply how the web works
