While true this can easily be countered, if scripts are made to simulate actual human behavior as opposed to maximum efficiency they will generally be harder to detect. You will still have the guys that run a plank maker for 20 hours a day and get banned because of it but it will help the people who bot intelligently. The people who change up what they bot, and don't bot for extensive periods of time will become far harder to detect as those patterns will take significantly longer to form. To take this one step further, if one were to develop scripts where a profile could be loaded in, such that the human behavior that is simulated is unique per user then detection would decrease even further.
