In the case of anonymity, people who perform threatening behaviors may use a variety of strategies to hinder tracking or identification. Here are some common strategies： 1. **Use anonymous tools**： -**Virtual Private Network (VPN)**: The real IP address is hidden through VPN, making it difficult for trackers to determine the user's real location. -**Tor Network**: Anonymous browsing through the Tor network makes it difficult to track the source of network traffic through multiple nodes. -**Proxy server**: Use a proxy server to hide the real IP address. 2. **Encrypted communication**： -**End-to-end encryption**: Use encrypted communication tools (such as Signal, Telegram, etc.) to ensure that only the sender and receiver can decrypt the message. -**Encrypted files**: Use encryption software to encrypt files to prevent unauthorized access. 3. **False identity**： -**Create a fake account**: Use false personal information to create a social media, email, or other online account. -**Use a pseudonym**: Use a pseudonym in communications or activities to avoid revealing your true identity. 4. **Anonymous payment**： -**Cryptocurrency**: Use Bitcoin, Ethereum and other cryptocurrencies for transactions, avoid using traditional bank accounts. -**Prepaid card**: Use a prepaid card or virtual credit card for payment, avoid using real bank information. 5. **Technical means**： -**MAC address spoofing**: Modify the MAC address of the device to prevent tracking through hardware identification. -**Operating system virtualization**: Use a virtual machine or sandboxed environment to operate to avoid leaving traces in the real system. 6. **Social media and online behavior**： -**Avoid using real information**: Avoid using real names, photos or other identifiable information on social media. -**Distraction**: Confuse the trackers by posting false information or misleading content. 7. **Physical security measures**： -**Use public Wi-Fi**: Use unsecured Wi-Fi networks in public places, which increases the difficulty of tracking. -**Avoid surveillance cameras**: Try to avoid being captured by surveillance cameras in the physical environment. 8. **Legal and privacy protection**： -**Take advantage of legal loopholes**: In some cases, take advantage of legal loopholes or privacy protection regulations to avoid being tracked. -**Privacy protection tools**: Use privacy protection tools and services, such as anonymous mailboxes, privacy search engines, etc. It should be noted that although these strategies can increase the difficulty of tracking and identification to a certain extent, they are not absolutely safe. Law enforcement agencies and security experts usually have advanced technologies and means to overcome these obstacles to a certain extent. In addition, the use of these strategies for illegal activities is illegal and may lead to serious legal consequences.
