And there we go.

This is exactly what exchanges which implement KYC with no warning are counting on. Privacy conscious users abandoning their coin(s). I'm not saying that's the wrong thing to do; I would do the same thing in your shoes with an amount I could afford to lose, rather than hand over everything needed to steal my identity to some internet stranger to then pass on to another stranger working for some third party.

There is no good reason to not give at least a week or two grace period. Not doing so is simply theft from users who don't want to send their documents. Even if I were inclined to complete KYC on an exchange, I sure as hell wouldn't be doing it on an exchange with such blatant disregard for their users. I hope others take notice of this before signing up to this exchange.
