We continue to emphasize the need for inter-, cross-and anti-disciplinary work on online abuse and harms. These include but are not limited to: NLP, machine learning, computational social sciences, law, politics, psychology, network analysis, sociology and cultural studies. Continuing the tradition started in WOAH 4, we invite civil society, in particular individuals and organisations working with women and marginalised communities who are often disproportionately affected by online abuse, to submit reports, case studies, findings, data, and to record their lived experiences. We hope that through these engagements WOAH can directly address the issues faced by those on the front-lines of tackling online abuse. Speaking to the complex nature of the issue of online abuse, we are pleased to invite Mona Diab, Murali Shanmugavelan, Gebre Gebremeske, Daniel Borkan, Lucas Dos Santos, Alyssa Lees, and Rachel Rosen to deliver keynotes. In addition to our invited keynotes, we received 47 submissions out of which 24 were accepted. Of the accepted papers, 20 were long papers and 4 were short papers. These papers will be presented in our poster session. We thank the reviewers for their dedication and efforts in providing in-depth and timely reviews. With this, we welcome you to the Sixth Workshop on Online Abuse and Harms. We look forward to a day filled with spirited discussion and thought provoking research!
