Depending on how important traffic from France, or wherever the IPs lives is to your site and to you personally, You can block entire countries. With WHM it can be done directly through the control panel- get your host to walk you through it..I don't know about systems

The premium version of the Word Fence plugin allows you to do it from you WP dashboard. I had some issues with the Premium Word Fence, so pick a time when it's slow in case there's a conflict and you have to disable the plugin..

There are several countries I no longer hear from
