Another thing I keep finding in my blog statistics are vampirestats. You see a url that seems to refer people to your blog. This makes it look as though more people have visited. Beware - they want your clicks. When you go to their site to see who they are, then they get what they want. I don't know how to block them - one person said that when a blog is established they drop off.
I've been saving the zombies and vampires and waiting for Halloween. Happily there are no horror movie diseases among my diagnoses so the only thing left that fits a Halloween post is the trolls.

Trolls are those people who jump into your discussions and disrupt them. They may insult you and others. They may argue or say outrageous things just to get an emotional response. The advice given on many sites is "Don't Feed The Trolls"
