This problem has been already solved, by making the "Nothing to Mine Here" script when you finish breaking rocks, which makes auto-clicking hard, most likely impossible. The mine collapsing is just "extra protection" to reduce macro. Warping players to other levels after a while in mining is a bad idea because if someone is actually there and not using the macro programs, this could be annoying to that player returning to his/her mining spot. And there is no staff in every mine level to check 24/7 if there is a player who is cheating or not. That is a player's job to do, and if you see someone who you think is using macro programs just report them.
