Meh... they're just words. Karazy is just enforcing the rules, we all know that if it was up to him, he wouldn't give a damn. about it. Even the NPC's use profanity. Just by looking at the files I can quote many examples. (It doesn't tell me which NPC says it, though.)
"Kino ****ed up his duties and is trying to flee from Par'Talucca."
"What the ****, you smell like ****. Where have you been for you to emit such foul odor? I ask for someone reliable and they send me scum like you. Tramps are all one and the same. Don't just stand there and come here.
"You sick son of a bitch. How can you so selfishly refuse a man who is dying right in front of your own eyes?
"Ha! I knew it! You're scared even before I tell you what the task involves. Get the **** out of my face you coward."
... So if I see a character named "WhatThe****" or "BitchBoy" get renamed, then the devs ought to clean up every NPC's mouth.
