Nobo writes: As seen in the CCP Announcements RDF feed, CCP has formally responded to the (alleged) source leak. In summary: The code is not a leak, but rather is decompiled python client code. The server is designed to distrust clients and sanity-check data to and from the client with the intent of ensuring no exploitability, even in light of known client source. The official client is digitally signed. And finally, despite widespread rumors, no mass banning has occurred as punishment for possession or downloading of the 'leaked' source.
