Here Samir not his real name tells the story of how he was trapped - and below the BBC's Reda el Mawy visits the Moroccan boomtown where many of the scammers are based. This girl added me on Facebook. I didn't think it was anything strange - I often get friend requests from old school friends who I don't know well.
The next day she sends me a message: I saw your profile and I liked you. With a girl like this, you lose your head That night she starts messaging me via Skype. She says she's 23, her parents are dead, and she lives with her older sister in Sidon, Lebanon.
She says she's bored because she doesn't study or work and that her sister is very strict. I ask her about her hobbies and she says she likes sex. She loves it, she says. But I was bored, my girlfriend was out of town, and didn't have anything to do. So I figured, "What the hell, I'll chat with this girl and see where it goes.
So I turn on my video and say, "Can I see you too? With a girl like this, you lose your head. We continue chatting, but only in messages, not actually speaking. She says she's afraid her sister will hear her. As we're chatting she tells me that talking with me is turning her on. I'm thinking because she lives with her strict sister, in the south of Lebanon rather than in a more open place like Beirut, maybe she's frustrated and looks for sexual encounters online. Then she asks me to show her my penis.
So I show her my penis. Then I say, "OK, your turn. I'd never seen anything like it. It was so easy. Too good to be true. So I start masturbating too. She tells me to put the camera on my face because it excites her, so I move the camera back and forth between my face and my penis. After a few minutes she pretends to have an orgasm. Still naked, she comes back to the keyboard to chat with me.
She asks me what I do, and I tell her I work in marketing in Milan. Then she says she hears her sister coming, so she gets dressed and signs off. He starts sending me insults, telling me he'll send the video to my mother, to everyone I know A half hour later I get a message on Facebook. Do you want to see it? It's about five minutes of me masturbating. My first thought was to send him the money immediately. ShameOnline This is one of a series of stories looking at a new and disturbing phenomenon - the use of private or sexually explicit images to threaten, blackmail and shame young people, mainly girls and women, in some of the world's most conservative societies.
Explore all the stories and join the conversation here. So I plead with him. I tell him I don't have 5, euros. He says, "Of course you do, you have a good job in Europe. You have one week to send me 2, euros. Otherwise, I'm sending the video to your family. If I send him money, what is to stop him from coming back and demanding more? Then he sends me the link to the video on WhatsApp - I feel sick to my stomach Then it occurs to me that if he sends the video to my contacts - people he isn't friends with - it will go to a junk inbox that no-one checks.
And even if they check it, I figure, who is going to open a video file from an unknown person? It could be a virus. So I have two choices: I send him the money and I have no guarantee he doesn't ask for more, or I refuse and hope no-one looks at the video. Then he sends me the link to the video on WhatsApp.
I watch it again. It's me masturbating, on YouTube. I feel sick to my stomach. Immediately I start reporting the video to YouTube for sexual content.
I report it, close the page, reload the link, and report it again. Image copyright AFP He sends me a message saying he's about to send the link to my relatives on Facebook if I don't pay. Of course I do' I couldn't pay him. First 2, euros, then perhaps 5, Where would it end?
He was so upset. He starts sending me insults, telling me he'll send the video to my mother, to everyone I know. I keep reporting the video. Each time I'm watching the number of views to see if anyone else has viewed it.
After about an hour YouTube takes the video down. From what I can tell, all the views were mine, except for one. That could have been him viewing it after he uploaded it, or one of my relatives. I'll never know for sure, but I've never heard from anyone. Maybe a male relative saw it and never told anyone.
Can you imagine, though, if an aunt had seen it? She would have told another aunt, her husband, her kids, soon my whole family would have known. And what if my mum sees this? A video of me masturbating. I would have thrown myself out the window from the shame. After the video was taken down I didn't hear from the guy again. I imagine he moved on to bigger fish. I remember when I asked why he was picking on a poor young guy like me he had said, "You think I don't target rich guys in the Gulf states?
Of course I do. You're lucky I can see from your Facebook page you're not married, or I would be asking for a lot more money. Reda el Mawy writes: The "year-old Lebanese girl" who seduced Samir on Skype was almost certainly a young man from Oued Zem - a small town in central Morocco that has become known as the capital of the "sextortion" industry. The Oued Zem scammers trawl Facebook for victims, and as soon as a man answers a video call - either on Skype or, increasingly, within Facebook itself - they activate software that shows the victim a pre-recorded video of a girl downloaded from a porn webcam site.
They are so familiar with this video that they are able to chat-message their victims at exactly the points where the girl appears to be typing on the keyboard. This is filmed with his face on screen so the video looks credible. When we've got the recording we upload it to YouTube and send it to him in a private message.
That's when the threatening starts. We spend 20 minutes chatting, 20 minutes for the video, and 20 minutes threatening - threatening and negotiating. So you look for their weaknesses, and you exploit them. The other weakness is when they are married, for example. You can exploit that. Then there are the really religious guys. You see someone who looks like a sheikh, carrying the Koran, and you think, 'There's no way he'll fall for this - but let's try him anyway.
I counted at least 50 international money transfer offices in the town. In the UK, Wayne May runs an online community, Scam Survivors, that offers advice and support to victims of the webcam masturbation racket. Since he has received more than 14, requests for help from victims all over the world, including the UK and the US. Many are young Arab men, he says, and about a third of all the scams originate in Morocco. Before the advent of social media, Oued Zem was largely reliant on remittances from people working in Europe.
But with the economic crash of , remittances dropped - and this was exactly the moment that Facebook and webcams were becoming everyday tools of communication. Salaheddin El-Kennan, a labour activist, does not blame the town's young men for making money from extortion. He points the finger at the state-owned company that mines phosphate in the surrounding countryside but employs very few local people.
Nationally, unemployment is at 8.
