What is Best Minecraft Anticheat Free Version ?

Your list of plugins looks good but If you have a 1.7 or 1.8 server you can use Wolf. I used to love the plugin because it basically not only prevents people from hacking but it is a really good plugin if you want to detect hackers. The plugin will notify all op players in the server (or predefined groups of players like moderators) about the player, where he is, and the hack he is a suspect of using.
