I have been thinking about how I've been reading a lot of topics from scammers who give themselves away easily by saying they recover bitcoins and I've been wondering how are these scammers finding about Bitcointalk when some regular people have not yet discovered this forum on their own.
Don't underestimate those bastards they might already know your name and email address. People who are good in social engineering become more and more better based on the number of their experience from scamming. That's why those bastards evolve and get more information the more they interact and wants to make their first victims.
