There is no such thing as a "fake" wall. Once an order has been placed on the market it is there and ready to be executed. People put up and remove walls all the time, but most walls are too small to notice. People like to pay attention to big walls and sometimes alter their trades based on it. It sounds like you are grumpy and my guess is that you got burned. Welcome to the free market. I hope after a few more years you'll learn to appreciate the liquidity that such walls provide for large holders. I personally would be delighted to see more big walls appear, it will give me more confidence in the market. For I could quickly get rid of my position by dumping into such "fake" walls, the more of them appears, the more opportunities I have to do so.

Instead of getting mad for what you deem to be "manipulation" and "fake walls" I encourage to take advantage of your knowledge and turn it into profit.
