In the anonymous review system of the school, students can take the following measures to leave negative reviews while trying to avoid being discovered: 1. **Choose an anonymous platform**: Make sure the platform used does support anonymity and the review will not be associated with any personal information (such as IP address, login information). 2. **Pay attention to language style**: Use neutral and professional language, and avoid using unique expressions or common phrases that may reveal personal identity. 3. **Specific but not personal**: Focus on describing specific behaviors or events, rather than making personal attacks or subjective speculation. This can increase the constructiveness of feedback and reduce the possibility of being identified. 4. **Avoid excessive comments**: Do not post comments too frequently, especially with similar tone or content, so as not to attract attention. 5. **Pay attention to details**: Avoid mentioning information that may uniquely identify a specific time, place or event, and these details may reveal your identity. 6. **Time selection**: Choose a non-peak time to comment to reduce the identifiability of user activities within the system. 7. **Diversify feedback**: If the feedback system allows, combine positive and negative feedback to provide a more comprehensive and less obvious review. 8. **Reference to other reviews**: Check out other students’ reviews to make sure your feedback style and content doesn’t appear too unique or out of the ordinary. This makes it safer for students to use anonymous review systems to express their opinions, but they also need to be careful about whether the content of the review complies with the school’s rules and policies.
