There have been some lively discussions in the forums lately regarding the details of the PPX antimanipulation regulations. Today we amended the rules with some clear language about these issues.
PPX was created to gather information about the PopSci audience's opinions on the likelihood that given science and technology predictions will come to pass. To maintain the integrity of that information, and to keep the game fun for the thousands of people who have become PPX members, we've tightened up the rules to put the emphasis on individual, human decision-making. Operating two or more accounts in conjunction is not allowed; nor is using a script to log in and/or make trades for you. Please read the revised rules, in the About section of the site. Questions? Contact firstname.lastname@example.org, or ask Yog-Sothroth in the forums. —PPX Admin
