Investigating the dynamics of illegal online activity: The power of reporting, dark web, and related legislation

This paper aims to shed light into the operation of SafeLine, the only Greek Hotline for illegal online content, and its seventeen years of successful operation as a member of INHOPE, the International Association of Internet Hotlines. The operation of SafeLine is introduced and an analysis of the received reports during its operation is attempted, in order to reveal hidden trends over the seventeen years. Furthermore, a comparison between the reports of SafeLine and the reports of the other 48 national hotlines, members of the International Association INHOPE, operating in 43 different countries spanning six continents worldwide is presented.
