Technically, "commercial scale" can mean anything from "someone somehow made money while doing it" (e.g. from ads to pay for hosting) all the way to "how someone doing it for money might do it" (e.g. using a proxy or fake contact details). It's intentionally vague.
This section specifically says "not carried out for commercial advantage or financial gain", so it doesn't apply to people who actually make money from this. I don't know what section that's covered in though.
