Hi, I am building a service that verify a person's identity by his company email address, just like what facebook does. I'd like to scrap all the email address domain of companies. Is there a major source of info for me to do so? Thanks, yamyam
google! lol theres lots of email scrapers about, try some blackhat sites for the tools to use also use whois to check site ownership if you have alot of time try searching google for "KEYWORD" inurl:contact
There might be a major source but I dont think you will find that it is a avalible to the public, I think facebook probably built its database manually....but I dont think anyone knows...
