One of the basic requirements of me using the free ‘IP2Location’ WordPress plugin for my blog is that its authors ask for attribution, which is fair. So here it is:
I just installed and configured the country blocking plugin from https://www.ip2location.com. I found it after a quick web search led me to this page: https://blog.hubspot.com/website/wordpress-plugin-to-block-countries.
The setup procedure is pretty simple: install it from the WordPress dashboard, sign up for a free account at IP2Location to install the database and stuff, and setup the block rules for countries or IP addresses.
(I didn’t want to pay Wordfence to extend their so-far excellent monitoring and blocking service, at least not yet).
