Welcome to POTCO comrade.
Seriously, I have noticed for a while that Disney has this Nazistic reign over chat. It has always bothered me, always irritated me to the max. As for why there is this secret filter, I dunno. I have spread the word to people in guild for as long as I could remember, and now I live in fear. Heck, maybe one day soon the POTCO secret police will arrive and carry me off to the Rambleshack again, where I shall be subjected to horrible torture and forced virus downloads onto my computer. Then my broken and sobbing pirate shall stay there for eternity.
Just sayin'. :P
