I'm not sure, but I think the software that generates these forums are American, in princible having an auto-censor is a good idea, helps to keep things polite and free of foul and abusive words.
You could argue it is against free speech, who the hell are faceless programers to tell me what words I can and cannot use
Obviously on forums such as this one, such language and behavior would not long be tolerated by the moderators.
Pop into just about any chat room, the younger the age group, the worse the language being used.
It's easy to circumvent these restrictions of course, and it does cause the odd wry smile when you read a post that becomes unintentionally funny as a result of a word being PC'd into something daft
Some of the stronger words come out in full though
Whats that about!!
I tried typing a coulple to see what they would come out like, I removed them sharpish when I saw they weren't changed into something else!
