I have a thought and if it has been done before I will be very happy. If not can somebody tell me if it is possible. Tracking cookies are probably the most used method of tracking users as I understand it. Could you have a plugin which messes up the tracking by generating fake tracking cookies. One way you may be able to do it, is by creating a shared database of cookies that could be used to corrupt the tracking data obtained. IS this possible or should I stick to my tin foil hat?
