Robots are supposed to send one.
Oh that’s interesting, so it’s actually somewhat doing what it’s supposed to do as a “nice actor”.
Should be more explicit though and users should be able to opt out.
For example I had Claude code up integrations with the Federal Reserve, and I pass my email there. They request clients do so.
When fetching a website it's not a robot any more than my browser or curl are.
These two do not share my email and real name with everyone who wants.
