A lot of people do not understand the purpose of Proof Of Developer. POD is to verify that the person claiming to be John Doe is really John Doe. However, John Doe can still scam people if he wants, POD will not stop that. What POD will do is hold people accountable for their actions. So for example if John Doe creates a scamcoin and runs off with 200BTC, the community now knows who is responsible and can take appropriate actions.
