Co-share network constructed from the Twitter_Covid. Given the density of this network, we aggressively filter it for visualization. We first keep the 10% of edges with the highest weights and the 10% of nodes in the innermost core (\(k=4\)). Then we apply the multiscale backbone method [59] (significance level 0.3) and retain the giant component of the backbone network. Colors represent credibility score: orange and purple for high- and low-credibility accounts, respectively; unlabeled accounts are in gray. Node sizes represent core numbers: smaller nodes are in the periphery of the network
