A point I made above is that they are too easy and cheap to create to ignore. If we had been on the fence about using them and they existed on 9/10/02 the next day would have decided it for most of the country. Ignoring the area is a bit like ignoring malware and virus development. The question to me is how do you discuss and control something this easy and risky? Mind you this is going to happen. I am sickened by the idea but anyone who is read or watched American Sniper knows the question and the outcomes. Anyone who can program a SBC can create one that would pull the trigger without question.

You hit on a good point. The exchanges don't want market makers getting out of the game. When I worked at a "England Based News Service" I saw brokers take market making VERY seriously. So while I agree the "little guys" really did the same thing that a bunch of other "big guy" where doing, I also see that hurting the market makers in a systematic way is bad. And that is what they did.
