Solved How to stop chat hacking?

How do you stop chat hacking?
In the console it can show up as
"
<*NyanWorld [Owner] samrg 472> test
01:56:18 [INFO] <*NyanWorld [Owner] samrg472> Welcome
"
the first line is through hacked client and was not me. It was some guy on some client and cant figure out the cause of that. The second one with the time was actually me. Any plugin to stop this?

 

Is your server in online mode?

 

Yes the server is in online mode. The name of the guy must be premium in order to log in. But for some reason these little hack messages are possible. >_>

Really not even sure how this is possible to being with.. offline mode or online mode. But my server stays online mode.

I'm not quite sure what you mean by "Chat Hacking". What's wrong with your chat?
It might just be a plugin's problem or something.

 

No this isnt anything wrong with my chat. I use PEX chat manager. Have online mode.
And its kinda hard to explain chat hacking but theres a hacking client that lets you stay stuff with anything and console wont log it with time or info and it will just say some thing like you could do
"[Admin] player; im going to ban you all" exact name spoofing.
on console it shows exactly like that but without the time or info logged which means its someone using a hacking client. But I have no idea how this is done or if a plugin is able to stop this.

 

Try NoCheat.

 

He left now. But I have NoCheat installed now to. Hopefully it will be stopped

 

Glad to hear that your problems solved. Please put a [SOLVED] at the beginning of your title so other people know that this problem has been solved.

 

I know in 1.1 its possible to use hack clients to change the the color of your chat messages without plugins maybe its also possible to change everything in the message?

 

I had this happen before. All they were doing is using /me or putting lots of spaces before entering your name.

Not hacking, just appears like hacking.

 

Then how would this excessive spacing be stopped?
