Botnet Statistics [2009-12-19]

After I utilize the data collected on the new detection system, the number of detected bots rose suddenly, and then took a sharp downfall. Now network operators seems to respond very fast upon my notifications. It is very good that my system seems to work, but I was wondering, is its own effectiveness going to drive itself into extinction, just like the (now gone) ORDB (Open Relay DataBase)?
