The rise of social media platforms has led to an increase in cyber-aggressive behavior, encompassing a broad spectrum of hostile behavior, including cyberbullying, online harassment, and the dissemination of offensive and hate speech. These behaviors have been associated with significant societal consequences, ranging from online anonymity to real-world outcomes such as depression, suicidal tendencies, and, in some instances, offline violence. Recognizing the societal risks associated with unchecked aggressive content, this paper delves into the field of Aggression Content Detection and Behavioral Analysis of Aggressive Users, aiming to bridge the gap between disparate studies. In this paper, we analyzed the diversity of definitions and proposed a unified cyber-aggression definition. We examine the comprehensive process of Aggression Content Detection, spanning from dataset creation, feature selection and extraction, and detection algorithm development. Further, we review studies on Behavioral Analysis of Aggression that explore the influencing factors, consequences, and patterns associated with cyber-aggressive behavior. This systematic literature review is a cross-examination of content detection and behavioral analysis in the realm of cyber-aggression. The integrated investigation reveals the effectiveness of incorporating sociological insights into computational techniques for preventing cyber-aggressive behavior. Finally, the paper concludes by identifying research gaps and encouraging further progress in the unified domain of socio-computational aggressive behavior analysis.

The UK's Scientific Advisory Group for Emergencies (SAGE) advised the government to introduce mandatory hotel quarantine for travellers arriving into the UK two weeks ago, according to minutes from a meeting on 21 January that were leaked to the Times. On Thursday 21 January, SAGE reportedly warned that "reactive, geographically targeted" travel bans couldn't be relied on to prevent faster-spreading coronavirus variants, such as those identified in South Africa and Brazil, from reaching the UK, adding that: "no intervention, other than a complete, pre-emptive closure of borders, or the mandatory quarantine of all visitors upon arrival in designated facilities, irrespective of testing history, can get close to fully preventing the importation of new cases or new variants." A Downing Street spokesperson said SAGE did not directly advise UK prime minister Boris Johnson to close borders. Universities minister Michelle Donelan told Sky News that the government "always based our decisions on the best medical and scientific advice" and said "the SAGE advice actually said it would probably be ineffective, in fact, to close the borders, which was the same advice that we got at the time from the World Health Organization". Johnson announced geographically targeted hotel quarantine measures for travellers returning from 30 countries, including Brazil and South Africa, last week. UK health minister Matt Hancock urged people living in postcodes in England singled out for enhanced coronavirus testing for the so-called South Africa variant to stay at home unless "absolutely essential". Urgent door-to-door testing for the faster-spreading variant has been deployed after 11 cases with no link to foreign travel were identified in parts of England.
