In the anonymous situation, people who carry out threatening behaviors may use a variety of strategies to hinder tracking or identification, including but not limited to the following: 1. **Use of Virtual Private Networks (VPNs)**: VPNs can encrypt network traffic and hide real IP addresses, making it more difficult to track. 2. **Proxy servers**: Use proxy servers to connect to the Internet to hide real IP addresses and change the user's geographical location. 3. **Deep Web and Dark Web**: Use tools such as the Tor network to access the deep web or dark web to avoid monitoring and tracking. 4. **Encrypted communications**: Use end-to-end encrypted communication tools (such as Signal, WhatsApp, etc.) to communicate, making the content of information difficult to eavesdrop on. 5. **Fake identities and temporary accounts**: Use fake identities or create temporary email addresses and social media accounts to conduct activities to avoid being associated with real identities. 6. **Use of anonymous currencies**: Use cryptocurrencies such as Bitcoin for financial transactions to further hide transaction records. 7. **Regularly change devices and locations**: Frequently change the devices and network locations used to eliminate regularity and reduce the risk of being tracked. 8. **Clear digital footprint**: Regularly delete browsing history, cache and other digital traces that may reveal your identity. 9. **Social engineering and disguise**: Use social engineering methods, such as pretending to be someone else or using false information to mislead investigations. Although these strategies can improve anonymity to a certain extent, they do not mean that they are absolutely safe and untraceable. Relevant law enforcement agencies and cybersecurity experts are also constantly developing technologies to deal with related threats.
