Rate the content of the message, not whatever happens to be linked from it.
Marking someone's message as vulgar for that is no better than marking it as vulgar because it contains a quote from another character with vulgarity in it.
In this particular case, the message was along the lines of: "Please read this, which I wrote: [link]".
It's not really abuse, the text linked was quite long, posting it on the wiki was the right thing to do.
