Honeybadger calls the page specified, abstracts how the form collects information, and then generates a fast flow (not a flood) of random information to the form's endpoint. After several thousant entries have been made, the scammer is unlikely to waste time continually testing the records, as the chances of finding a genuine set of credentials is almost impossible.
