  2. Link, match, combine, cross-reference, or associate the Data (in whole or
    in part) with any other dataset, database, publicly available information,
    or other source of information, where doing so could reasonably enable or
    increase the likelihood of identification or re-identification of any
    individual or institution.
  3. Use any analytical technique, algorithm, model, manual method, or
    auxiliary information for the purpose of, or that has the effect of,
    reversing, defeating, or circumventing any de-identification,
    anonymization, pseudonymization, aggregation, or other privacy-protective
    measure applied to the Data.
  4. Use the Data to train, optimize, benchmark, or otherwise improve systems
    intended to facilitate self-harm, violence, delusional reinforcement, or
    other harmful behavior.
  5. Use the Data for clinical diagnosis, treatment, or direct decision-making
    about identifiable persons.

    screening, law-enforcement profiling, or other non-research deployment
    contexts.

6. Security and Incident Reporting

Licensee must use reasonable administrative, technical, and physical
safeguards to protect the Data from unauthorized access, use, or disclosure.

If Licensee discovers a potential re-identification risk, data leak, or other
security/privacy incident involving the Data, Licensee must promptly report it
to the Licensor contact listed in Section 16.

policies governing human-subject and sensitive data research.

Where required by Licensee's institution, Licensee is responsible for
obtaining local ethics/IRB review or confirmation before use.

10. Term and Termination

This Agreement is effective upon first access to the Data and remains in force
