Vendors also list guides on how to commit other illegal activities.The documents are often sold for small amounts of money, but the price barrier, the need to pay with Bitcoin, and the fact that they're only available on the deep web prevents the guides from being circulated widely.
That's the final step, as the scammers leave with thousands of dollars, and the storyline has finished.
It’s time to change the way we do dating in the UK.
Bitcoin is cryptographic currency favoured by criminals as it allows semi-anonymous online transactions.
It's not just guns and drugs that are up for sale on deep web sites.
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 author claims that someone who operates the scam can earn up to ,000 (£9,700) every month if they operate the dating scam full-time.
After a week, scammers are told to call the target and claim that their "husband/father/pimp/whoever" got "drunk/high/whatever" and attacked them.
Then they will ask the target for thousands of dollars in order to run away and escape forever.
Well, first of all, Adhrann suggests that readers look for certain types of men: "40-60, technical or financial formation (IT, analyst, accountant, consultant, engineer, etc); lonely, or still living with parents, poor social/conversational skills, shy, a bit weird, nerd type, etc." So if that sounds like you, stay alert.
