The majority of work has been dedicated towards detecting misinformation with some focus on analyzing the flow of fake news across social networks. However, there is less attention to the characteristics of social media users who consume this fake news. In this work, we investigate the possibility of predicting users' reactions towards fake news and defining some network characteristics for each users' group. We utilized a set of fact-checking websites in the Arab world that report social media posts spreading fake news and the interactions with them. We defined three sets of users: 1) Spreaders, who spread fake news, 2) Checkers, who constantly share fact-checking threads, and 3) Refuters, who respond to fake-news posts declaring their inaccuracy. We build a classifier that uses users' network graph to predict their reactions with an accuracy exceeding 93%. We applied further analysis for the most significant features of each users group and noticed that spreaders interact with more accounts that use their mother tongue, a considerable number of famous state-sponsored accounts, and accounts that get suspended while checkers and refuters interact with more foreign accounts and news-reporting entities. Central nodes in the networks of spreaders were found to be linked with state-sponsored media, whereas central nodes in the networks of checkers included organizations with a cross-cultural nature.<\/jats:p>","DOI":"10.1145\/3653702","type":"journal-article","created":{"date-parts":[[2024,4,29]],"date-time":"2024-04-29T10:05:31Z","timestamp":1714385131000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["\"Pinocchio had a Nose, You have a Network!\": On Characterizing Fake News Spreaders on Arabic Social Media"],"prefix":"10.1145","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8239-3333","authenticated-orcid":false,"given":"Mahmoud","family":"Fawzi","sequence":"first","affiliation":[{"name":"School of Informatics, The University of Edinburgh, Edinburgh, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9676-1338","authenticated-orcid":false,"given":"Walid","family":"Magdy","sequence":"additional","affiliation":[{"name":"School of Informatics, The University of Edinburgh, Edinburgh, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,4,26]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1609\/icwsm.v15i1.18114"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/3359307"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipm.2021.102597"},{"key":"e_1_2_1_4_1","volume-title":"Proceedings of the Sixth Arabic Natural Language Processing Workshop, 231--236","author":"Ali Zien Sheikh","year":"2021","unstructured":"Zien Sheikh Ali, Watheq Mansour, Tamer Elsayed, and Abdulaziz Al-Ali. 2021.
