Some Schools Districts crack down on inappropriate blogs

"Maintaining or being identified on a blog site which depicts illegal or inappropriate behavior will be considered a violation of this code."

Now that sounds pretty benign, but can you really control what is posted on a blog?  For example, I know we all hate it when Jason post's stuff about Evangeline Lilly.  But is there really anything we can do about it?  Except maybe help out the Bump Evangeline Lilly Contest?
