Personally, I would take it as a little extra literary challenge to make fun of the person before deleting their comment. Those are the ones with an attitude, and they should get some of their own medicine back. Remember, folks don't mind being told about their vices, but don't like to be reminded of their weaknesses. So, they may take deleting as a challenge, but will cave in after looking funny, while knowing that others are reading it about them as well. I don't mean telling the person that they are an "idiot" or something, but showing that their comment is ridiculous and they don't know what they are talking about, and maybe they should stop embarrassing themselves. Well, that's me, I don't play a victim so easily.
