Grounded in Social Capital Theory, this study examines the tension between popularity as a form of social capital and its limited capacity to predict rigorous credibility assessment using a global quantitative survey of 500 social media influencers across multiple languages and regions. The findings suggest that influencers with larger follower sizes utilize more diverse sources; however, follower size does not correlate with credibility assessment rigor. This underscores that follower size functions as a symbolic rather than epistemic resource, where source diversity often serves as a visible signal of professionalism rather than having a deeper verification. Additionally, credibility assessment rigor is not a significant predictor of source diversity, and platform type and content genre did not moderate the relationship between follower size and source diversity. These findings contribute to the influencer marketing literature by challenging assumptions linking popularity with higher scrutiny of content credibility. The study holds implications for platform policy, media literacy education, and influencer\u2013brand collaborations. Recommendations are provided for improving transparency and source vetting among digital content creators in increasingly flooded social media platforms.<\/jats:p>","DOI":"10.3390\/info16110958","type":"journal-article","created":{"date-parts":[[2025,11,5]],"date-time":"2025-11-05T17:06:06Z","timestamp":1762362366000},"page":"958","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Does Follower Size Matter?
