Then they will ask the target for thousands of dollars in order to run away and escape forever.
That's the final step, as the scammers leave with thousands of dollars, and the storyline has finished.
It's not just guns and drugs that are up for sale on deep web sites.
Vendors also list guides on how to commit other illegal activities.
It's pretty easy to tell: They send the same message over and over, often with the same link.
But there's a type of dating site scam that's far trickier to spot, and the people who operate it claim to be making thousands of dollars every month fooling vulnerable men.
The document, titled Adhrann's Updated Dating Scam 2014, lays out a method for creating fake dating site profiles, ensnaring men in conversation, and then pressuring them to send money.
The guide isn't available for free, in fact, it was being sold for Bitcoins on a deep web marketplace.
Bitcoin is cryptographic currency favoured by criminals as it allows semi-anonymous online transactions.
They are then instructed to take the information learned, and then create the "perfect woman" for the target.
Adhrann says that scammers should "emphasize on you being in a difficult financial situation, yet DO NOT insist on that, but treat this subject like you have been much better in the past, and really ashamed now, [as you are] not used to being poor." Step three is where things start getting really interesting.
