Due to the annoyance of Gil Spammers and seeing GM's or SE don't do much about it realy , at least not on my server .... i would add a suggestion:

Add Custom chat filters , so we can block phrases/ words like " w ww / www / w w w etc.
This will help us blocking certain unwanted messages.
We already do have a chatfilter for profanity.. so why not add one we can customize to our own needs

I also would love to see the " rightclick name and add to "blacklist" option
