My friend got banned, and hasn't been able to withdraw much for a month. Yesterday, he managed to grab 2 first-come-first-served opportunities at the studio, but today he got passed. His deposits may not be much, but he makes 1-2 transactions of 8000u every day. Looking at his withdrawal times, I don't really understand how to determine if someone is a retail investor or a studio now. Is the first thing to do when opening Binance every day to nervously check if you've been banned?
