I think the context here is that em dashes are usually generated verbatim from LLMs? I haven't seen them generate a lot of double hyphens; I suppose the post could be laundering them to double dashes, but if you're gonna try to hide LLM prose just drop them entirely? [please correct me if I'm wrong and double dashes are also an LLM tell - genuinely don't know]
