On a serious note: you can actually go into your profile controls and turn off your ability to hover, as well as the notifications that tell you who hovered over you. But where's the fun in that??

(Holy crap, I hit level 7.8 responding to this post! Excellent.....)

I look at my profile daily and find that someone hovered. It must be a new fad. If not, you are being reported for looking at words or something.

As Woody Allen observed, in The UFO Menace:

The most frequently asked question about the UFOs is: If saucers come from outer space, why have their pilots not attempted to make contact with us, instead of hovering mysteriously over deserted areas? My own theory is that for creatures from another solar system "hovering" may be a socially acceptable mode of relating. It may, indeed, be pleasurable. I myself once hovered over an eighteen-year-old actress for six months and had the best time of my life.
