I know this isn't really open for discussion, but what makes me uncomfortable is that there aren't clear rules about what is/isn't allowed. The other night, on the in-game chat, someone used the word "penis" in a completely appropriate and non-sexual way, and someone else warned them about the PG-13 policy.
That seemed like an overreaction, based on not having clear guidelines. I've heard that particular word used in prime-time network TV shows. Who exactly are we concerned about offending with a proper anatomical term? Are there really 13-year-olds who don't know what one is?
This is just one example, but there have been other times when I know people have felt inappropriately stifled. It's a tricky question, because the thing that brings us together is, by its very nature, sexuality. Obviously we don't want people propositioning each other in the chat channel, but on the other hand, this can also be a safe place to role model healthy sexual attitudes for our young brethren and sistren. (Yeah, I just made that word up. Sorry.)
