Michel,
It has been thought but doing it will simply make some members to post more unappropriate content online by simply taking words from the dictionnary that wouldn't be in such list. You and I both know that this is not a legitimate answer. Rules can't work if they're not clear and consistent.
I'm one of the individuals who helps support your forum. While I pledge my continued support for the UT, I find recent actions questionble. Another post to follow.
