Long story short, people continually spam the shout box. Frankly, it's gotten overly annoying. From now on anyone who posts in the shoutbox asking for the Terraria password will receive a ban of 24 hours. I don't care if you're just joking.
Learn to read directions and stop spamming the shout box. Consider this your warning.
That is all. Terraria mods, edit this policy as you see fit.
