Hi there, I am looking for a good anti freecam plugin for the server I am playing on at the moment as the staff are too incompetent to even search for one themselves. I have tried looking on the web but I cannot find a plugin that I can recommend to them. At the moment on the server hackers can freecam any distance and it is getting very frustrating for those with bases that are nuke and glitch proof but open to hackers. Please help me out, I am very desperate. Thank you very much.
