Scrpae Emails from Facebook Pages

Hi,

I know there are many threads about this issue but I still couldn't find any definitive solution.
I simply want to scrape all Email address from Facebook Pages for a given keyword. Most Pages got email address on "About" section.

I heard about simpleaudiens - is anyone still using it? is it working for what I need? do I need to use it on my own Facebook account? if so, are there any limitations?

Thanks
