Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
Shortly, no global filters will be done.
When I have some time, I can implement user-defined filters where each user can define a list of words he doesn't want to see. But I don't expect to do it soon because any run-time filters slow down other processes which is never best for BrainKing.
