<p>In the face of escalating global crises and a rising number of victims, this study examines the challenge non-profit organizations face in garnering public support for multiple victims compared to single ones. Specifically, it explores whether social media cues can help overcome donor apathy toward multiple victims. This study proposes that the perceived supportiveness of a fundraising campaign enhances perceived impact and self-efficacy, leading to supportive intentions for multiple victims, overcoming the tendency to focus on a single victim. The findings demonstrate that in messages featuring several victims, high perceived supportiveness leads to more favorable attitudes toward the fundraising campaign and greater willingness to support victims than low perceived supportiveness. Additionally, high perceived supportiveness can elicit perceived impact and self-efficacy, leading to more favorable campaign outcomes. The results indicate that the perception of supportiveness on social media plays a crucial role in encouraging supportive intentions for multiple victims, potentially going beyond the identifiable victim effect.</p>
