That said, my motivations include both self-interest and interest in others. If you want to see what outcome would ensue if I changed my motivations (e.g. "what if you were only interested in yourself") you could prompt the pro-spam position much more efficiently by asking about more directly pro-spam motivations -- e.g. "what if you were interested in seeing more spam on the network." If you tune the motivations properly, you can get any response you like.
