Social media, dating platforms, advertising and aid platforms, forums and messaging applications, and other online platforms are often "hijacked" by criminals involved in human trafficking for sexual and labour exploitation. On 6 September 2022, a joint action day involving more than 20 countries, and supported by Europol and Eurojust, targeted criminal networks using websites and social media platforms to recruit victims for sexual or labour exploitation. As a result of the "hackathon", 114 online platforms were monitored, 11 suspected human traffickers and 45 possible victims identified, and criminal intelligence gathered for further investigations and monitoring.
