No matter how we dislike these bots I'm absolutely sure we must not set the fork point in the past, only in the future, because this would totally compromise the coin (even if no significant transaction cancels). This bot doesn't violate any rule so we must not take away his coins.

Also, we need to discuss the next anti-bot patch.

I just want to repeat my suggestions (I still think they will work):

1) No matter how clever this bot is, he still requires to enumerate thousands of maps. We should make map generation really slow process that require a lot of hash work (you can take some average pc and tune this alghorithm so that it require 2-3 sec on average). It would definitelly be inconvinient for people but we must do it. Don't invent complex anti-warp algorithm etc, just make this hash work constant and huge.

2) We should slow down solving process too by requring around 1 sec of hash work every 3-5 seconds of playing and mix founded nonces in the physics (alter velocity, acceleration etc) (this changes should be significant, it should be impossible to ignore them). I know the game will hang sometimes (when hash is not ready yet), but I think we can accept it. Also this would require us to enlarge proof of work significantly (we'll have to save our hash nonces somewhere) but this step is really neccessary.

I've believed and still believe that these two steps will kill all current and future bots for months or even years.

You will probably not be able to mine with your bot too, but you have already proved that you don't care too much about it.
