While scrupulously blotting out his own belle gueule, he made no attempt to hide the women's faces, leaving them easily identifiable in his before-and-after photos.
This became a temporarily diverting topic for his fellow 'mongers' online, men with nicknames like Spurter, MeatMan and XXL whose idea of an ethical debate usually consisted of whether or not to tip for oral sex without a condom.
'He gets my vote for poster of the year!' gushed one, though another warned: 'These girls are Muslims. They live in a Muslim country. You are exposing them to grave danger.'
When the forum moderator suggested covering up the women's eyes, some members countered that there was no need: their faces were already covered in semen.
THE TRAGIC OUTCOME
Belguel's images soon began making the rounds in the local souks, and in 2005, the fiancé of one of the women recognized his betrothed on a black-market CD.
Despite the obvious question of why he was watching porn in the first place, the Moroccan did the me-so-macho thing and beat up the woman, an otherwise respectable schoolteacher.
Rejected by her family and friends, the woman tried to report Belguel to the police; tragically, she was arrested instead: in Morocco, it's a crime to pose for explicit photos.
The disgraced teacher was fined and sentenced to a year in jail, while the police tracked down the other women on the CD.
At last count, thirteen had been sent to prison (two reportedly tried to kill themselves) and several others had disappeared: presumed suicides or the victims of 'honor' killings.
It turns out that the true criminal in the case had been caught with porn pictures and questioned by the Moroccan authorities the previous year.
'The police kept me in for eighteen hours, but they released me because Morocco has good relations with Belgium, where I am a well-known person,' Belguel crowed later.
With the cooperation of the Belgian police, though, he was eventually unmasked as not just a run-of-the-mill perv but a baby-faced member of the country's media elite: Philippe Servaty, the chief economics correspondent of Le Soir, Brussels' most influential newspaper.
Although he apparently hadn't committed any crime under Belgian law, Servaty was forced to resign: not for abusing the women… but for making 'racist' remarks about them.
He's since gone into hiding with a bounty on his head.
