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.
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.
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.
Celebs like Will & Jada, MoNique & her husband, and even Brangelina have been open about dabbling in this lifestyle.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.This screenshot shows a user of a hacker forum being advised that a quick way to find sets of photos is to automatically download them from Facebook: Even before a scammer messages you, you can spot they're fake by checking their photos.Performing a Google image search for an account's profile picture will show you where on the internet the image appears — sometimes you'll see it attached to Facebook, Instagram and Twitter accounts with various different names.
