Is that really a thing? That must be such a hazard for their developers. I usually have a test for sites that I work on, that scrapes a few URLs as Googlebot, to verify that they are getting an optimized view (no JS, structural-only css).
Yes. Googlebot only crawls from legit addresses (even when their developers are trying new things) so it's an easy scraper/scammer signal to key off of.
