This one case in Sweden, Gotheburg in 2012 came randomly in to my mind (explanation about it below) and I was thinking did other countries had a big scandals related to social media? TW! I also remember the blue whale game from Russia started to shore to other countries.
”The Gothenburg 2012 Instagram Case was a major social media scandal in Sweden. It involved an anonymous Instagram account that spread defamatory and explicit rumors about teenage girls in Gothenburg, accusing them of being promiscuous. The account quickly gained attention, leading to widespread outrage and a violent protest outside a school in December 2012, where over 20 people were arrested.”
