I love the idea of a user-controlled filter in the options.
"Do you want to use filters?"
Yes.
"What words would you like to block?"
Perhaps with a parental-controlled password, in case kiddies go back and change it.
By the way, 13-year-olds aren't adults, I forget who said the game isn't geared towards 'children,' it's 13 and up...but 13 year olds are kids, and parents can be very protective and get angry.
If there is at least an option to control words kids can't see, everyone can go on using them as they please, which from what I see is what people seem to be fighting for. I know in much more adults settings I've played in that I got frustrated with filters myself. Why? Because I wanted to swear. I can't really imagine why else people would dislike filters, unless the scripting of the filters was done poorly. There are definitely ways to script so that, for example, you can say "scrape" without it being blocked for the obvious word contained within it.
