They need to put in things like random requests for response that need a player to OK that or something or the game stays frozen for that player until they do. Have some variable coded requests so its not the same code requesting a response every time, even require a different response everytime, for example a code to just display a message 'in text' asking the player to send a mail to 'botchecker'.
Clicking OK on the dialog won't unfreeze the game, the player would need to fire off a test email to 'botchecker' to get it to continue. A bot can't logically respond to verbal requests.
