Ask HN: Why does LLMs love the usage of –?

It was really uncommon pre-ai that you saw the usage of — in emails. So I wonder why all LLMs default to it so often?

An example;

GoDaddy: only needed if we end up moving DNS hosting off Squarespace. If so, delegate access is cleanest — from Account Settings → Delegate Access, invite {emal} with "Products, Domains & Purchase" permissions (full login works too if that's easier). One thing to flag: the domain currently has GoDaddy's update lock / Domain Protection on, which blocks nameserver changes — you may need to lift that for the change to take.

It's such a giveway for AI-generated content that I prompt "Please don't use – in any of your responses."
