We moderator the forums highly enough, I don't think the filter is require here.
As for filtering content in general, Innectis is aimed at a wide target audience, in order to do this, certain issues such as indecent content and swearing need to be dealt with. Although the internet is full of these sorts of things, we need to do as much as we can to encourage a friendly enviroment. There are a large amount of very protective parents who do not want their children exposed to this sort of thing, for this reason we restrict it. There are a fair few places on the internet that restrict things such as we do, so we are not the only ones ^^
