What most people don't understand is that the main issue that most of us are seeing is not that our sites are getting hacked or that we're in danger of them guessing our password. The issue is that there are 1,000+ login attempts in a couple of minutes. This crashes many servers with it accessing PHP and MySQL. All of the plugins that need to access PHP and MySQL to "check" an IP or perform any operation on the database doesn't help against this.

Does anyone know if this plugin has to check the database or use PHP in order to check the IP blacklist?
