Just read this post (I'm working backwards from the last I commented on). I guess I would probably favor option 2 to prevent abuse. That said, I agree with fauwy that even if people do try to self-buy to get more PKM that ultimately would benefit peakmonsters and the token.
But to be honest, some of the what you wrote is beyond me so I will have to take some time to understand.
Ok, on to the next, er..previous post.
