I got this error using codex "Error running remote compact task: unexpected status 403 Forbidden: This user's access to gpt-5.3-codex has been temporarily limited for potentially suspicious activity related to cybersecurity. Learn more about our safety mitigation

I'm not doing anything related to cyber security I was just trying to create NPC players to run a simulation on a video game I'm developing. I believe this is a false positive.

The problem has been mitigated. We're resetting rate limits to compensate everyone for the inconvenience.
