Product: GSC (Game Servers Client) Version: 2.00 Build 3017 Website: http://getgsc.com By sniffing the traffic of the chat client one can easily discern that it uses IRC to back its private messaging system. From there, you can simply issue commands such as NICK and switch your nickname to any other user's nickname on the network while they're offline, bypassing chat authentication. From this point, you can utilize the client's interface to send messages from the new nickname. With this, you can also avoid being kicked out of a "chat channel" (IRC channel) when you're banned from a voice chat server; you'll be able to speak in chat still.
