Do you mean when someone enters the URL to the avatar in the custom URL box at another site? It won't even work because the contents of the avatar file will be text (the redirection message). The board (if it's vBulletin, anyway) would give an error message saying it's not a correct file type or something.

If they use an IMG tag to link to it, it will show up as a red X, and when someone drags the link to it into the address bar or puts a URL tag around it, it will link to the redirection notice and the profile page.

I don't see why protecting one's bandwidth from getting stolen without the person viewing the site it's getting stolen from is such a bad thing, unless you have hundreds of gigs to give away, but if it's not for you, then just don't install it. (holy run-on sentence batman!)

You don't have to attack the people that prefer to use it.
