GameRager: Yes but wanting to encourage people to not post such in titles but allow such in thread posts? Why allow one and discourage the other in such a way if not for a totally different reason(Such as getting new customers to come to GOG.) than just encouraging board civility?
because of context. A headline will always be out of context, it is to indicate the topic which is found in the thread. The topic of a thread will most likely not be focused around swearing, so why should the headline? In that case it is just attention seaking (I generally as a rule do not bother with thread which have "bad words" in the headline as it an indication of no content...)
However, when you are writing a post/argument/what-ever in the tread, you are trying to get a point over to the reader and in that context "bad words" can be used to insert some emotional impact.
The difference is like shouting swear words at random people passing you by in the street, or using them in an argument with someone.
