Who enforces this?

So far the AI companies care for nothing.
They stole all content of the entire internet and seem to be getting away with it.
So why would they care about such a license?

A license file can't force an unwilling crawler. What moves it is evidence. When access goes through a gateway that checks the terms and signs what it decided, an operator can show it respected RSL terms, and a publisher can check how its work was used.

I built an open reference of that flow. One request is refused before the work is loaded, another is allowed, and both decisions are signed. The agent's output carries a signed attribution record back to the work, and anyone can run the verifier:

Today it runs on a CC BY-NC work with a custodian-signed access condition. I'd like to adapt it to read RSL terms directly.
