I remember a guy who had a very successful Shuta Bot back in the day. It was programmed to only pick Shutas. It could differentiate the drop.fail, there isnt such things
For sure I never saw the bot program, but I do recall he was negotiating with some guys to design the thing to spec, and a little while later - he had a lot of Shutas to sell. I found his Bot working once or twice. This was at a time when there was no double drop and shit. This was back when it was tough to get Shutas and they sold for $$$$.
