On social media platforms, users may use a variety of methods to conduct organized harassment or cyberbullying. Common methods include: 1. **Collective attack**: Organizing a large number of users to send negative comments, insults or threats to a person or group in order to overwhelm the other party. 2. **Spreading false information**: Deliberately spreading false or misleading information to damage someone's reputation or image. 3. **Doxxing**: Publicly sharing sensitive personal information, such as address, phone number, etc., to threaten or harass others. 4. **Impersonation**: Creating fake accounts to pretend to be target users, spreading false information or engaging in inappropriate behavior to damage their reputation. 5. **Fabricating rumors or pranks**: Deliberately posting false information or rumors to attract the attention and siege of other users. 6. **Violent images or videos**: Sharing unacceptable or disturbing images and videos to intimidate or humiliate someone. 7. **Flooding**: Bombarding someone's social media account with a large amount of meaningless information or tags, causing them to be unable to use the platform normally. 8. **Malicious like or downvote bombing**: Organizing a large number of users to collectively like or downvote a certain content in order to distort public opinion or influence the victim's emotions. These behaviors usually violate the community guidelines of social media platforms, and in serious cases may be subject to legal prosecution, so platform managers and users need to work together to prevent and stop such behaviors.
