This plugin is use solely for messing with other people. Under no circumstance should it be installed on a public server. This announces the player's IP not your server's. I am not responsible for the bullshit that comes from this.
There is no way to toggle on and off the plugin, it is either installed or uninstalled. However if this shitty of a plugin gets 10 downloads I'll add a toggle feature. The only other thing to mention is that the output for when somebody join is (players name "'s ip is" IP "Welcome to Brazil") Along with sending the player that joined a gif saying "I have your IP" or something like that I forgot, beside the point, be careful installing this plugin cause it literally leaks IPS.
