CPA offers and email

Currently when I open my personal Facebook, there are literally hundreds of people posting their private emails in public domain ( not my friends, I frequently visit Buy and Sell type groups ) .

Surely there should be a way to scrape these mails and sending them a CPA by mail.

Have any of you done something like this before and did it produce worthwhile results. I'd hate to spam them, but they kinda asked for it when posting this in public domain ( I promised myself I will look away when pressing the send button on this offer )

You could try that i think there is some scraper around, just don't get caught in the process

Will most likely not be doing it, just curious . And I believe there would be others not so "nice" people that would But man people are stupid. I mean, how targeted do you need ?
