I know some websites say in their terms and services that the website can only be accessed by humans and not bots or scripts. How do they tell who is accessing? Especially with tools such as AutoScript that just record the mouse movements and keyboard input, wouldn't it appear fairly natural? This is assuming there are no additional security features like captchers.
I'm guessing if the log files show that the user had been repeating the exact same actions with the exact same timing, this would be a red flag. But wouldn't this be hard to check for?
