My guess to the root of the problem - and it's a guess - is that those that sold on the market board, the pros that kept within the rules, earned too much. I easily made 1-2 million a day, and I didn't even work hard for it. Those that really worked hard could easily make 5 million a day. SE saw this and found it to be unacceptable, so they decided to let the bots run free, to keep the prices down. This is a short term solution, as it will have unwanted consequences, something SE probably will find out, if they haven't already. In addition, if I understand it correctly, this isn't much of a problem on the Japanese servers, because the Japanese players are much more willing to follow rules than us westerners, who basically, in most cases, will disregard any rule, if we can get away with it, so SE don't really care much about it. To explain this means I have to get into the word 外人 (gaijin), something I'm hesitant to do, as it's a very sensitive subject for the Japanese.
