I don't think that this would work in any meaningful capacity. If we limited the newbies to a newbie board, then the bots would just continue to farm the way they do within the newbie board until one of their bots acquires the merit to break out of that board and into the rest of the forum. It wouldn't stop the bots, but it would simply change the way they operate; this isn't fruitful in my opinion. Any actions taken against them should be significant enough to remove the incentive for them to do what they are doing, else it will continue.
