I made a Facebook web scraper which opens 20 headless browsers. You provide a list of unlimited usernames & proxies (you can buy them at https://buyaccs.com/en/). It will scrape every ounce of public information available. I acquired a few million users worth. The data is too easy to get.
Which kinda throws me off. It's no secret Facebook, Twitter, your phone (if you give permission to a 3rd party app) etc, are all harvestable. All CA is in regards to a story that broke a couple months ago. Why is it catching fire now?
