I've tried using their tool to report them one at a time, it's quite tedious.

I've tried emailing them at info@facebook.com. Redirected to support page.

I only care because FB is the first hit when you google my name and FB suggests connecting with these impostors on their logged out landing page.

Besides writing a bot in Selenium to scrap FB and report each profile, I'm not sure what to do. Any ideas?
