Scraping Emails from Facebook Fan

Is it possible to scrape emails from Facebook Fan Pages?

With FindOnPage I get 0 results.

You can use the Facebook connector -> Page Lookup (found in the Social category) to get page emails:

Thanks ! Is there a limit ?
I added 470 Facebook URLs and I get nothing... Thanks !

Yes, there is a limit but it's difficult to calculate, depends on many factors. 470 should be possible. Does it work with one URL? If not, then you need to logout/login and during authentication in browser, give SeoTools access to at least one Facebook Page that you own.
