Science is reinventing play, from extreme sports to gamification to ridiculous roller coasters to the playgrounds of tomorrow, and this issue is chock full of fun. Also, on a less fun note: Did global warming destroy my hometown?
You do get "penalized" for switching from a buy to a short. You get charged $0.25 per share for selling/covering then another $0.25 for buying/selling. So are you saying that there should be more than a $0.25 commission for each share traded?
Also, why do you think users have multiple accounts?
because they have no life
I agree with pso7025. PPX did not always have commissions, they were added to create the penalty for regularly flipping positions or bluffing to create wealth.
As for people having multiple accounts, one person decided to get rid of their accounts in another thread and listed the 3 accounts they had active. I'm sure he's not alone, although I believe there's little advantage to it, and it would eventually get caught.

It did work previously. We one had a class join PPX. There teacher was teaching them about the stock market. The kids actually got together (if I remember correctly 3-5 guys) opened multiple accounts. With the other accounts 12-15 they would purchase or sell stocks after previously selecting the correct way with the account they wanted to count. This drove prices and made it all very erratic. GPM1942 was able to track it.
If there's a penalty, that's news to me. As I recall, there were commissions, then a lot of complaints, then they dropped commissions. I mostly stopped PPX trading after amassing about a million dollars. It's not about playing the market now, it's actually about making a prediction and sticking with it to the end.
