Chat Filter

Hi
Out of curiosity, why are some words only changed to @#!&% e.t.c, but some stop the entire sentence from being shown at all.
Also there is a certain word which can not be said and I really want to know why. I can't say it soooo.... I will describe it. It starts with 'V', ends with a 't', is 6 letters long and is the name of a flower or colour (at least that is all it means to me).
Thanks

You take a look at the known filtered words and dropped words here on the wiki.
The simplest explanation is that OOO does not want certain words to show up in their game in any context. All the different languages have recently had their filters combined, which has caused some seemingly innocent words to be blocked when they have a dirty meaning in another language or share the same letter patter as another foul word. This is a temporary hiccup that they are working to sort out.

I heard 'violin' is filtered too, due to the "viol" part... No idea what "viol" means in English, though :D
EDIT: looked at Wiki after reading d0gr0ck's post... that "viol" thingy seems to be something from French to me. Still no idea what it means :D
Why are the racial slurs for Asians not filtered? D:
Violet is filtered? o_o
