1. If you want to block an IP manually, you can do this by providing IP in admin menu "IP Blacklist->Add IP to Blacklist".
2. If any visitor try to login with bruteforce attacks or scripts, you can view IP and details on "Failed Login" and blacklist the IP.
For example: https://www.ip-finder.me/220.127.116.11/
3. Once you black listed the IP address, the visitor will not be able to view any content of your website and also post your website name on IP Blacklist Cloud.

5. You can leave comments on IP Blacklist Cloud so that other users can get the idea why this IP have been blocked by your site.
