I have a feeling that SE is sorta trapped in their current crafting situation. If they were to exterminate all of the bots, then crafting in its current form may become unsustainable due to supply costs skyrocketing and crashing the market. Because of this, they just turn a blind eye to the whole botting system on the crafting side. I have read about the sophistication of the bots in the media and they are getting to an amazing level. The amount of resources that SE would need to invest to capture these automatons would be incredible. I'm not fond of botting in any way and wish people would not do it but I don't see any way for SE to stop the current generation of bots with the resources they have.
