When you turn on the command, all the players around you are repelled. There is also a whitelist in the plugin. If you specify a nickname in the whitelist in the config, then it will not be repelled.
Since the plugin is paid, I do not leave you open source. Perhaps if people buy I will make a giveaway for the plugin for 5 people.
