Funnily enough I've had some issues with Binance recently, too. I've been using their services for many years, a binance card user as well with decent trading volume. A couple of weeks ago they started spamming me with "Source of Wealth documents needed" - I provided everything I had and after some time they backed off but then I got a warning because "You have sent and received funds to/from gambling services which is prohibited as per our terms". I searched through their ToS and they make no mention of gambling services, anywhere. When I pointed this out the reply I got was "This is our terms, do not receive funds from any gambling services or you will be banned".
I read all the nonsense that spammers from sig campaigns write in this thread, and I stumbled upon your post. If a week ago my experiences were fairly easy, now I am seriously thinking about withdrawing my funds from Binance as quickly as possible. The only question is whether it is worth using a centralized exchange to exchange and then withdraw coins from the exchange? I’m just worried that even if I don’t store my coins on Binance, but simply replenish my account in order to make an exchange, they can also block me without any explanation (despite the fact that I have a verified account).
