Account suddenly deleted, cannot log in to backend, saying something about review. At most, my account did scalping strategy. The main point is that when I was doing it, I kept asking customer service whether I could scalp. After doing it for a while, I asked again, and customer service said it was fine, and there were no restrictions on holding time. If you suddenly cannot allow scalping, you could tell me that the platform does not allow scalping, and I would simply withdraw funds and be done, rather than suddenly deleting someone's account and blocking the backend.
