To an extent, true. There are a lot of lazy ones though. And even for those who take steps, it sometimes leaves enough of a trace to at least raise the question.

I suspect people who think they are getting away with this are far more obvious than they realize.

One thing I think that helps is that for anything more worthwhile than message board posts like this I use Claude to review my text, make suggestions, and iterate on structure with me. But I'm the one writing the bulk of the text. I'll take some of its suggestions verbatim, but only if I genuinely like it better than anything I came up with myself.

The end product is something much more polished than anything I'd writ eon my own, but still comes off as being genuinely from me. At least that's what people have told me when I've asked.
