Hi HuskyPup -
Crawlers could be used for all sorts of reasons, and the relative difficulty in setting up and operating them has decreased as the technology matures.
That being said, we do know that these crawlers are generating invalid activity in the network intentionally or not, and our goal is to help ensure that publishers do not see such a large discrepancy between the estimated and finalized earnings when these clicks are filtered.
Hopefully that clarifies things.
