We conducted a design evaluation exploring whether a structured crowdsourcing system using trained volunteers could monitor and categorize election-related misinformation during the 2025 Australian federal election campaign. Over six weeks, 90 active participants surfaced 592 potentially misinforming posts and provided over 3,000 assessments across multiple platforms and recurring narratives.

We used a modified Delphi method to elicit and synthesize experts’ views on disinformation, misinformation, and malign influence (DMMI). In a three-part process, experts first independently generated a range of effective strategies for combatting DMMI, identified the most impactful barriers to combatting DMMI, and proposed areas for future research.
