You gave a stranger with no soul and no skin in the game the keys to everything you own.
@kepeken spacing paragraphs and using short sentences is not an indicator of LLMs. It's what we used to call "effective writing" back when I was young.
Which is why it's used by LLMs, of course, since they're trained on stuff that survived and is available (so, likely, the most effective).
Also, it's been the standard communication style on LinkedIn for several years as well so any corpo would probably try to emulate it.
