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

Em-dashes historically been very common in nonfiction and literature and are a very versatile way to compose more complex sentences and provide an alternative to comma-separated clauses, colons, parentheses, etc. I think AI is just reflecting something that fell out of common usage as part of a general trend of people reading less and paying less attention to punctuation and sentence construction. Now it's seen as a tell for someone using AI, but if you pick up any book written in the last 200 years you'll see tons of em-dashes.
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."
