Sexual harassment in the public sphere has been a growing concern in Egypt. The latest study commissioned by the UN women concluded that 99.3 %of the female participants has been subjected to some form of sexual harassment. Although this form of violence is wide spread and practiced on a daily basis in Egypt, yet there is no official numbers on these cases, as women rarely reports these incidences in the police stations. The challenge of collecting data on sensitive issues, such as gender based violence, is a well-documented problem across the globe. Stigma and shame prevent many victims of harassment and other types of sexual assault from reporting these crimes or discussing them with researchers. New technologies and social media platforms open up possibilities to overcome some of the reporting barriers. HarassMap is the first independent initiative to combat sexual harassment in Egypt. In 2010 it launched an online reporting system for individuals whom experience and/or witness sexual harassment. While crowdsourcing has increasingly become a valuable tool for many corporations, governmental and non-governmental organizations, it has not been without its limitations. There is considerable disagreement over the quality of the data generated via crowdsourcing . Lukyanenko and Parsons (2012) discuss the lack of domain expertise among individuals utilizing these platforms. In social science research, Schmidt (2010) looks at reasons why crowdsourcing has not taken off as a data collection strategy the way it has in other industries and mainly attribute it to two key point: sampling bias and the demographic make-up of the participant pool. This paper will present that findings of the study that was undertaken by HarassMap to validate the crowdsourced data collected from 2010 on sexual harassment.This study aims to examine the usefulness of crowdsourcing as a method of data collection strategy for sensitive issues, such as sexual harassment, in developing countries. It aims to answer questions like : what is the utility of crowdsourcing as a data collection method for sensitive issues in developing countries? How does the content of crowdsourced data differ from the content of data collected through traditional qualitative and quantitative methods?. Using more than 1200 reports of sexual harassment collected via HarassMap online map since 2010, the research comparatively examines these reports against information derived through more traditional data collection methods, including surveys, focus groups, and in-depth interviews.
