Facebook confirms that it tracks mouse movements
> Facebook said that it tracks mouse movements to help its algorithm distinguish between humans and bots.<p>Stupid cat and mouse game. How difficult would it be for a bot to simulate a human's mouse movements? I suppose not very difficult.<p>Also, doesn't this conflict with rare types of input devices? Or people with a motor function disability?<p>> to also determine if the window is foregrounded or backgrounded<p>Shouldn't there be an API for that?
