Aslam Walkum (Peace be upon you) Wordpress website admin to help people signing up with fake accounts

Aslam Walkum (Peace be upon you) Wordpress website admin to help people signing up with fake accounts. I have a wordpress website and a OCR plugin but I am not sure if the hacker is trying through other ways of getting into the website and signing up, the person is making fake accounts and I am not sure how they are doing it if there is another webpage to sign up on our website without the OCR, might be another webpage that does not have the ocr plugin on it. So it would be great to find out these things: 1. Where the hacker is signing up with these fake accounts on what webpage(s) on our the website. 2. To find out what IP address it is an block the IP address. 3. To see IP address in wordpress control panel. (might be a plugin or something that you know of, that I might not have installed yet). 4. If you know of any other means please share it that could help stop these hackers from hacking the website. Jazak Allaah Khrain (May Allaah Reward you with good).
