Or add .css to the list of extensions you've got in your current anti-hotlinking routine, if it ends in a flat-out [F] or 403.

If you link to a ferocious "no hotlinks" image, you might enjoy doing something analogous with the css. Rewrite (not redirect!) to a CSS that says, in full, something like

body {margin: -2em; font-size: 800%; font-family: "Comic Sans"; color: #F0F; background-color: #0F0;}

I just made that up, but you get the idea.
