Can you somehow prevent users who use hack clients to join my server? I dont mean "Turn server ONLINE mode", I talk about Nodus Client etc. other hack system clients. Can you somehow make them disconnect instead of joining ? Friend just found a DIAMOND DUPING GLITCH with Nodus Client & I don't like the idea that people use clients like that at my server. My server is PVP which means the hacker clients will help a lot, there is this spectate possibility, autojump from block to another block faster instead of space spamming to get up the blocks you can just keep walking and no need to jump. There is this where you can hit from like 6 blocks away a player and the player who you hit can't hit you back because it's not really possible unless you use Hack client like for example Nodus Client. So help me bukkit users! Can you prevent players who use Nodus Client etc. Other hack clients to join my server?
