I tried it once and they somehow decided I'm not worth, if I try again it fails with "We couldn't start verification. You may not be eligible for this verification flow right now. Please try again later, or contact support if you think this is a mistake.", not sure if they think I'm part of an APT or whatever.
I got it. Probably helps that I'm at a large company and my personal OpenAI accounts have spent probably close to $10k now (reimbursed by work).
It's helpful in reducing the guardrails, but there's still guardrails around security research that I bump into.
