you like many others are probably sick of the gold sellers in the chat, correct? well my suggestion is they add a captcha that you only have to fill out once when you log in to game to use the shout feature, you could also just email a code once every log in that you have to enter to use the shout feature, again it would only once on log in to use the shout feature you could still play without entering it if you didn’t plan on using the shout feature. Just a suggestion. really enjoying the game tho guys keep it up 
oh and add a level 50 cap on the shout feature so they have to at least work for it
