A lot of folks use the word "Gay" in a negative or derogatory statement. Same with Boobs - a large percentage of women find this as rude/derogatory.
Let's pile on the fact that a majority of Graal's player-base are below 12 and begin telling their parents these words. Prior to the word filter, I can't tell you how many e-mails I had to respond to about unhappy parents.
We are not re-instating the use of these words. While they may not have any derogatory meaning to you. However, society has deemed them such. I can't change that, sorry.
