That is very possible.

But it is not necessary to see the results that are being described.

If sites like my tiny little browser game, with roughly 120 weekly unique users, are getting absolutely hammered by the scraper-bots (it was, last year, until I put the Wiki behind a login wall; now I still get a significant amount of bot traffic, it's just no longer enough to actually crash the game), then sites that people actually know and consider important like acme.com are very likely to be getting massive deluges of traffic purely from first-order hits.
