Simple and basic plugin to automatize the control of abusive access to your WordPress. Simple because isn’t modifying your Wordpress too much, adding hundred of not needed functions or forwarding your data and control to cloud services outside your domain. Basic because do just what you need to control the access to your Wordpress. If you are tired of check your apache/nginx access log, check the abusive IPs activity on AbuseIPDB and block the access to them throw your .htaccess. This plugin does it automatically for you. Just get your API Key (on AbuseIPDB), setup the confidence of abuse threshold from AbuseIPDB and the plugin will check the IPs and add to the IP block list automatically. Also the support from the plugin author is fast and resolutive. And the best… it’s free. No limited functions or premium versions. The only thing missing is the ability to control the access by hostname, to be the perfect tool.
