extract twitter followers email

any software that can extract email addresses of our followers from twitters?
facebook is added to revtwt
having email address is really needed

Isn't there any internal way of finding out the email address? Beside I think the users would prefer to keep their mail accounts secret. Even some people has more accounts in the name of the same mail account.

nobody can help extracting?

I would think tweeters wouldn't want to have their emails available, that's why they tweet. I don't remember even seeing an option when signing up to make your email public or private.

Some people will have their emails on their page background graphic, but would be mostly marketers, and good luck with trying to scrape text from an image.....
