I don't think it's easy to manipulate the market, but this potential continues to be carried out by irresponsible people, as a result the market is increasingly chaotic and out of control.
Aren't the written rules so clear and don't ever try to break them?

Why does this keep happening, isn't the strict supervision already a deterrent effect, I wonder why these people don't think about other people, wasting time in useless places is a decline in thinking.

In my opinion, stricter supervision is needed, so that irresponsible people do not do anything arbitrarily, the effect of their treatment is not very good for the market.
