In online groups, cyberbullying against individuals is often carried out anonymously using the following methods: 1. **Anonymous accounts**: Using pseudonyms or anonymous social media accounts to carry out attacks, allowing the perpetrator to avoid responsibility. 2. **Social media platforms**: Posting malicious comments, rumors or spoof images through social media to carry out cyberbullying. 3. **Online forums and chat rooms**: Posting insulting remarks or attacks against specific individuals in anonymous forums or chat rooms. 4. **Malicious emails and messages**: Sending threatening, harassing or insulting content through email or instant messaging. 5. **Group attacks**: Organizing a group of people to attack a target together, such as launching a "siege" on social media, posting bulk comments or forwarding malicious messages. 6. **Fake identities**: Posting content in the name of someone else so that the victim thinks that the attack is launched by a friend or acquaintance. 7. **Cyber stalking**: Collecting personal information of the victim to harass or blackmail. 8. **Fake web pages and phishing**: Creating fake web pages or social media accounts to deceive the victim. 9. **Using third-party tools**: Using anonymous VPNs, proxy servers and other tools to hide one’s true identity. These methods can cause serious emotional and psychological harm to victims. It is important to strengthen cybersecurity awareness and legal protection to help victims deal with cyberbullying.
