I don't have anything to say about this plugin. I am just making this review to help counter the other dingus who made a false review about it (The source code obviously shows that it can't lag the server).
The description of the plugin says what it does. Just because a plugin is useless doesn't mean it's bad. The plugin does not squander the TPS of the server at all, if you look at the source code of the plugin, you will see that there is nothing at all that can load the server.
