Most bot systems make use of various human behavioral markers that could be grab as accidents, such as key presses, mouse interaction, taps, and scrolls, which usually exhibit certain delay. Bots, for instance, are quick to move straight to check boxes. This is not how human beings would behave or function. Such systems are highly efficient at distinguishing between a robot’s interaction as opposed to a human’s which makes it extremely difficult for bots to mimic a human convincingly.
