alt Hacker NewsPretty sure Anthropic and other providers prepend these "official" system prompts to your conversation even if you send in a custom system prompt otherwise it would be trivial to produce CSAM, etc.

I don’t think so. If you start a new Claude Code session without a system prompt, it doesn’t even know what model it is and hallucinates being some old variant of Sonnet.
The system prompt is (and cannot be) the only guardrail against things like that, because any system prompt is little more than a good suggestion.
I wouldn't put auch limitations in the system prompt. A mix of fine-tuning and out-of-band detection appears to be a better fit.
at least according to their documentation they do not
afaiu they have other systems for denying and re-routing requests
They use non-LLM gates for this.
Otherwise DANmode and similar jailbreaks would still be as easily accessible as they were at the beginning.
CSAM, and other harms, are typically detected using a set of specially trained, faster and cheaper models (and out of band matching techniques) that run before and after the main model.
Any mention in the system prompt is mostly defense in depth, and to make refusals more graceful.
