One woman sits at a desk and one stands behind it with a microphone, and a selection of their slides are projected behind them on the wall, depicting a wolf engaging a young woman in cam work, with subtitles such as "women only get 5%" and "sexting done by pimp (or bots)"

An illustration depicting a session where two female journalists describe impersonating other people online to infiltrate a rapist network. The two women appear 'inside' snakes, holding notebooks and pens, taking notes as they chat to the snakes around them. Bubbles containing their advice for safety when undercover appear around them: 'define your persona', 'stick to your rules: no encouraging', and 'check your mental health'.
