Never use WordPress without it

WordPress just isn’t worth using without this plugin, and that’s not an exaggeration. These days I see all kinds of “probing for vulnerabilities” results from none other than the Russian Federation company out of Cyprus Greece called STARCRECIUM LIMITED as an example. Company only registered 6/20 of last year, and yet they ping random sites. They are one of HUNDREDS OF THOUSANDS of examples. Blocking not just their ip address, but their ENTIRE SUBNET, is AWESOME! Re-routing and then instantly blocking ALL SUBNETS who attempt to access wp-login, ABSOLUTE GOLD!
