On one of the other forums I participate in, we had a similar conflict a few years ago. The owner of the board was concerned that anyone just coming by the site looking for legitimate information, including children, might stumble upon the material. So the solution was to create an "Adults Only" section that required you to PM the mod for permission to view. I personally don't have any problem with colorful humor, but I totally understand the opinions of the other side. I don't know if this kind of solution is something worth considering here, I'm just putting it out there.
