Hence lay the danger when dealing with these sorts of outfits. If these types of exchanges do not selectively scam their users directly by withholding funds and freezing accounts then they will always be in a position to sell KYC to criminals all over the web.
A lesson for all reading this post, never ever hand over your personal details such as photo id, signature and bank details to any exchange unless absolutely necessary and only when you select the ones with the best reputation.
Congratulations.
You've successfully given a bunch of Russian scammers that you don't know or where they are based all your personal & private information so that they can defraud & sell it to any criminal they want. Expect your first large withdrawal to be locked or your first large deposit to be stolen in the meantime.
