It seems that GAIJIN has not implemented any banning measures at all. I reported it several times before, and the administrators said they would check for violations. But before long, it started trading in-game currency again.
On top of that, the bot trading in the market is so fast. As soon as you place an order, it’s immediately outbid by bots at a higher price. I even suspect that their own staff have installed bot scripts on the market servers.
