Really just a few attempts at cybersecurity related things (not even RE) with ChatGPT/Codex triggered a warning of breaking ToS by email. A few days later I was banned. No appeal.

My conclusion is that OpenAI will help you with cybersecurity and never really block or prevent you from doing the work, but then suddenly warn and/or ban you. Anthropic does the opposite, where they trigger safeguards all the time while working, but never really ban you.

Also, while you may have never heard of this happening I found countless threads on Reddit with frustrated people having been banned from OpenAI for using it for cybersecurity. Since all I’m using AI for is cybersecurity, it’s hard to know exactly why I was banned since they don’t say exactly why.
