Sample input query in search bar is:
yang ( @[login to view URL] OR @[login to view URL] OR @[login to view URL]) AND site: [login to view URL]
Then paginate, extract emails from results page, save emails in txt, repeat with another query with different name and/or different site. Names database is to be taken from [login to view URL]
The above is for italy (it). Respective directories for 200 country codes to be added in Db. 100 country codes are in [login to view URL]
Only 1st (or 2nd) names to be taken in Db. Not full names as it reduces emails as results. Proxy rotation, etc. to be handled.
