I'm not defending nor agreeing with word censoring 100% I'm just making a statement that could be. Most of the forums will come up in a simple google search, without need to log into the site, so there maybe the thought there that we might offend someone, even a 7 year old or an adult. I don't know I'm just saying that the forum is viewable by many more than just the members.
I do agree that it is going to far.
What about in PM, are words censored there too. To me what you do in private (PM) should be whatever you want. What you do in members only section another and then on the publicly viewable forum yet another, but that's just my opinion.
