Has RaxBoard undergone an independent security audit and vulnerability assessment?

Hello,
I would like to know whether RaxBoard has undergone any independent security audits or penetration tests.
Specifically:
Has the software been audited by a third-party security company?

Have source code reviews and vulnerability assessments been performed?

Are there plans to use an independent security organization for future audits?

What measures are in place to protect forums against hacking attempts, exploits, and newly discovered vulnerabilities?

Is there a responsible vulnerability disclosure or bug bounty program?

Thank you for your time. I look forward to your response.
