I didn't face this problem. But my opinion if you change password by secrete question there is chance to block. But if you recover password by email, you shouldn't ban. I will suggest before attempt recover password Stake your Bitcoin address here , in case if your account ban you can prove yourself that you are owner of account. Problem is if admin find any suspicious behaviour on your account he might be ban for temporary. So better try to recover by email. But prevention is better then cure. I always write my password in hard paper( Diary).
