Based on the given proofs you have, it seems like your account is "too active" with thousands upon thousands of deposits and withdrawal which does not correlate to the age of your account (Aug 3, 2020) and having no KYC. In my point of view, this might be a counter measure of the exchange for money laundering since its rampant on the crypto industry.
You obviously did not even look or read anything that was presented. 9 deposits and 4 withdrawals is not mathematically equivalent or scaled to "thousands". Where did you get "thousands of deposits and withdrawals" from?
