Sexeaddicte43, as he calls himself online, was a meticulous client. After each paid encounter arranged through the website Sexemodel.com, he insisted on leaving long, detailed reviews. He rated the women according to criteria such as the accuracy of their photos, the cleanliness of the location, and their "enthusiasm" during the service provided. For Ibitissem75, he gave a score of 15/20: "She does what's necessary but remains rather mechanical, lacking a bit of passion," he wrote. Another client, using the pseudonym Harder888, was less verbose: "The young lady is very nice, she lets you enjoy yourself as you wish, while enjoying herself too, and lets you finish however you want." But he felt compelled to add: "Careful, gentlemen, she is very, very young!"

This alert reached investigators from the Paris Brigade for the Protection of Minors, who opened an inquiry into the profile of "Ibitissem75." Ibitissem did not actually exist; the alias was managed by Mansour C., known as "Bilel," age 37, who has since been charged with aggravated human trafficking, aggravated pimping, rape of a person engaged in prostitution, rape of a minor under 15 and direct incitement of a minor to use narcotics. Between May and early November, when Bilel was arrested, he was suspected of having exploited at least five girls, aged between 13 and 17. Three of them were under 15.
