I'm looking for millions of email addresses. These addresses should be from primarily Western Countries such as United States, Canada, Australia, New Zealand, and Western/Eastern European nations. Other countries can be included in the list just not make up the majority of addresses. I don't want email addresses for businesses, organizations and government agencies. I am looking for email addresses for personal accounts only.
As far as usernames go, I'm looking for usernames associated with popular websites. Social networking, Sports/Gambling, Adult, Dating, Retail stores, Auctions, Travel, Forums ect.
I will require a sample of 1 million email addresses or usernames. I have a database of over a billion addresses. I need to ensure I am not buying a list that I already own.
