I'm not sure if this is something that can earn money consistently for long periods of time. It takes just one person to leak logs for all others to lose curiosity and stop playing the game. Sooner or later, some scrupulous gatekeeper is going to release logs. That's also part of the reason why I have my hesitancy to play significant number of games.
Well, it could be possible to make some sort of in-browser java or flash application in which it'd be impossible to copy text or store logs. You could still take screen shots of memorize things though.
AI Box Experiment Update #3
Tuxedage (AI) vs Alexei (GK) - Gatekeeper Victory
Tuxedage (AI) vs Anonymous (GK) - Gatekeeper Victory
I have won a second game of AI box against a gatekeeper who wished to remain Anonymous.
This puts my AI Box Experiment record at 3 wins and 3 losses.
