why not have their parents use the e-tard filter and expand the vocabulary to filter.
This is a game that's supposed to be acceptable for children from the get-go. If someone goes up to their parents with such a request, the parents, though there is a solution, might be upset with the game and ban their children from playing it. So they enforces their rules despite their ignorance to avoid a loss of their game completely. I know people that have had similar issues with games and their parents with a loss of the game as the end result.
While I can understand it can be hard to stop yourself from saying those words aloud, you have no excuse not to be lazy and just not type them.
