If you've used a dating site or app like Ok Cupid or Tinder, you'll have noticed the hundreds of fake profiles that exist on the sites, seemingly designed to make you hand over your profile to scammers.
Dating sites are, thankfully, getting better at spotting who is using their service to send thousands of spam messages.
It's called the "cashing out" stage, and it's where scammers start to ask for money.
Up until now, scammers were instructed to turn down any requests for a Skype call, but if the target insists, then they should ask him to pay for a webcam.
Another way to spot whether an account is fake is the selection of photos that it uses.
Adhrann's guide says that scammers should "look on the Internet for a bunch of pics of a cute girl" and select someone who is "not a top model, but a normal sexy girl." To find photos, scammers can buy sets of photographs of young women, often through shady forums frequented by hackers.
So how do you know if someone is trying to scam you?
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.
That's a sure sign that the account is fake, as the photo must have been circulating on the internet.
Step two in the dating scam guide deals with "developing a virtual relationship." Scammers are told to ask lots of questions about their targets, paying particular attention to their past relationships.
Scammers are told to use a female partner for the video call part of the process, but there are guidelines on what they should look like: If a scammer is successful here, and managed to con the target out of money for a webcam, or other small amounts, then they may attempt the riskiest part of the process, known as the "pause." Scammers are instructed to stage an altercation over webcam, and then cease contact.
