he network diagram contains three main clusters, each centred on a distinct labelled node. On the left side of the diagram, one large cluster is centred on “Reddit dot com slash r slash scihub”, from which many surrounding connections radiate outward. Toward the upper right, another dense cluster is centred on “Sci hyphen Hubdot se”, forming a hub connected to multiple external nodes. Slightly below it, the third major cluster is centred on “410610 dot org”, with its own set of outward connections. Some of the labels included in each cluster are as follows: Cluster 1: Reddit dot com slash r slash scihub: “Twitter dot com slash Protohedgehog”, “engineuring dot com”, “Uproxx dot com”, “Nature dot com”, “Redditinc dot com”. Cluster 2: Sci hyphen Hubdot se: “Researchgate dot net”, “Reddit dot com”, “Twitter dot com slash ringo underscore ring”, “T dot me”, “Academia dot edu”. Cluster 3: 410610 dot org: “Es dot ht”, “82 dot 77 dot 83”, “Sci hyphen Hub dot vk”, “Gumroad dot com”, “Hubg dot org”. Some other small clusters are also included, such as “Sci hyphen Hub dot ee”, “Sci hyphen Hub dot st”, “Libgen dot rs”, “m dot Facebook.com slash Sciencehabit dot com”, “V K dot com”.Graph showing the Sci-Hub domains crawled
