Among other tell-tales, Grok can identify posting patterns that are different between humans and bots.
Humans actually go offline for hours at a time.
Bots post ‘round the clock ‘cuz they never sleep.
I don’t know what the internal process is when Grok identifies an account exhibiting bot behavior, but I’m aware there is a mechanism in place for that, and it’s coded into the daily functioning of the site.
