Does Google Know if We Post Spun or Generated Content

Large sites seem to be getting away with it.

I'm pretty sure a large percentage of some Q&A questions are auto generated and/or spun from 3rd parties.

If the quality is good enough no issues for you probably.for example I have a software I build this does articles but unique ones for me when I am to lazy or can't be bothered hiring someone to do it for so far my ranking keeps going up since I started it with my sales going up so far as well.

If you proofread it well, you won't face any issues
AI-generated content has more indexing rate on my end
