Annoying chat spam limits social interaction
Social interaction is one of the most important aspects of WoW, and chat is the most important means of communication. Unfortunately, the possibility to chat is repeatedly destroyed by spammers who post the same advertisement every few seconds. The player posts the same line every five seconds (!) in the trade chat. For hours, for days: "WTB Cardinal Ruby 225 Gold each COD ME ALL YOU HAVE"
That means that only this single player posts the message 720x per hour (!) in the chat.
I know I can set it to Ignore; but is there no way, no interest in solving the problem in principle, by setting a limit, e.g. posting the same line only every 3 minutes?
