I think someone like Esvelt (and also Greg, who personally answered in the affirmative) will probably respond. Even if they are too busy to do a call, they’ll know the appropriate junior-level people to triage things to.
To build on Linch’s response here:I work on the biosecurity & pandemic preparedness team at Open Philanthropy. Info hazard disclosure questions are often gnarly. I’m very happy to help troubleshoot these sorts of issues, including both general questions and more specific concerns. The best way to contact me, anonymously or non-anonymously, is through this short form. (Alternatively, you could reach my colleague Andrew Snyder-Beattie here.) Importantly, if you’re reaching out, please do not include potentially sensitive details of info hazards in form submissions – if necessary, we can arrange more secure means of follow-up communication, anonymous or otherwise (e.g., a phone call).
