Good point. I think some bots, not all bot, will highlight short comings in the current system. It might make sense to modify the system in response, e.g. to prevent manipulation of the system in some way. I do however think there is a benefit to keeping some bots as bots. For example, there might emerge a rival to @wang that serves the same function but does so more effectively. By not incorporating @wang into the system we are allowing peoples subjective opinions to decide with of these bots best serve a particular function.
