The problem is that a met spammer has to have a considerable framework in place before it could even hope to work. Inventory enumeration, item usage, item properties, packet handlers etc... Any program with that much already in place is going to do more than just met spam. COAI has zillions of features, I doubt the average subscriber would use a fraction of them, just as the average photoshop user never touches 90% of all the stuff it can do. You get it because it has the feature or the features you want, the other stuff it can do is incidental.
