If bots are an issue, we have to ask our selves why players would decide to use bots instead of actually play the game? It all depends how many bots we have and how many real players we have, but I'm assuming there are a ton of bots otherwise we would not be talking about this issue. This tells me that given the current state a lot of players currently would rather use bots than play the game. Maybe the answer is to find out why that is and try to address the underlying issues. Is it that the game takes too much time or people feel that the the fun and amount of rewards earned from playing is not worth the amount of time it takes? Or is it just that people try to get an edge by using a bot. Keep in mind that any anti-bot measures could drive away a large portion of the game that is currently using bots. I always thought the plan was to make it so that bots don't have an advantage over humans not try to stop them.
