Not sure where to put this but yeah, it appears the word filter in the Message of the Day is preventing some valid words being written.
It seems to work by outright stopping you being able to type a naughty word, and not just preventing a message containing naughty words from being published.
I'm trying to write "assuming" but it won't let me as I have to write "ass" in order to type it out.
I can type hassle and harass, so it seems to only prevent a word being written if it starts with a blocked word.
Hardly a big deal, but yeah... I want to be able to make assumptions! Haha.
