A bit of a spamming problem

A lot of the guests on creative are constantly spamming the chat. People keep telling them (I have as well) "If you are in the same area, (which they are) please use /ch l". They won't listen. It is starting to become a bit of a problem. I will keep this posted with some screenshots soon and some more updates of it if it continues.

EDIT:
Got the screenshots

 

Trying to get my screenshots too this page. Sort of stuffing up for me so can someone give me a good site or a bit of a tutorial?

 

press f2 go to your minecraft folder take the screenhot to you desktop upload it to photobucket copy the img link here

 

THANKYOU SO MUCH. I had the screenshots ready but I just didn't know how to upload them. I'll have the screenshots in a few hours.

 

Just btw, we do have a tutorial on the forums in server guides and tutorials

 

/ch leave gc should do the trick

 

and /ignore [player] to be even more specific

 

I'm locking this thread, I cant get my screenshots to work and the problem might not continue. (I hope it doesn't)
