After making a profit, I applied for a withdrawal but was unable to do so. They directly stated that risk control had determined it was a violation, without giving me a reason. They blocked my account with 2000 USDT and wouldn't let me get it back. An email said the review was approved, but I still couldn't withdraw. Later, they told me it was a violation and my entire account was frozen, refusing to let me withdraw anything, and simply asked me to write an account abandonment form.
