Since there is Ventrilo and Team Speak, its kinda useless in a way as people can communicate anyhow for raids, group hunts,. etc.....
It would only clean the Gen chat.... making it then a spamming place to sell objects.... so replace insults for mass amounts of items for sale.
Well organised guilds/hunting parties all already have some sort of exterior communication system set up.
Now who is going to police all the reports, remember that our dev team is 5 people, then maybe say 8-10Ems and whatever GM there is on if there is any known.
Dev, EMs wont investigate it, so that leaves it all onto the GMs which we dont know how many there are and if they gonna be overflown by requests.
