The whole idea of the no swearing rule has quite a few things to it, some bigger, some smaller and many people have different views on how this should be tackled.
However, if people want FeralHeart to remain up and online then rules like this one is needed. The majority of the users that do go against this rule does get caught sooner or later, and it's in all honesty, not a hard rule to follow either. By no means does using a lot of curse words/foul language make you look more mature or adult, what it does do however if used to often is to make you look like an immature child that need to expand your vocabulary. If you swear someplace else I couldn't care less, I personally even think that swearing is not that bad, but if you go on a game like this one, know there's a wide audience of players of all ages and background, and it always had a set rule of having appropriate behavior and language, and you still go with your foul language, it you do need to rethink a thing or two.
It's also been proven to myself, from taking part in other game communities in the past, that the overall game or forum environment and quality becomes a lot better when it is followed, overall just more welcoming and more civil and it is something that many users, believe it or not, comes back to. Now things could've been way better if information could be more easily accessible from the game about such things as rules or just communication over between site and game, this is really an old thing to beat on though since that don't appear to be happening anytime soon. We have what we have though and we try to make the best of it. Even if more drastic and less fun changes must be taken, it's all done so for the better of the game at this point.
Everyone that been playing FeralHeart for a while, and still come back to play it knows that they want the game itself to be around. But sadly, many users do not come in contact with the rules until after they already got caught breaking them and skip reading them all together, and if not that..
It's just that some people cannot pay respect to the rules or other users in general, and proceed to act like any other place on the internet, all places really does have rules of some sort, the only real difference from FH and other bigger sites(not smaller) is that swearing is more open, while we want to keep a more friendly environment for everyone, doesn't matter if you are 7 or 25 years old.
