I don't know how to fix it NOW, but the way to prevent it in the future is to not make your email address visible or via link on any website. For example, instead of
johndoe@johndoe.com, you may just put john doe AT john doe dot com. That will at least shield you from the Spambots. On my blog, I use a contact form for people to contact me; that way I don't have give my email address.
Sorry if this is not at all germane to your problem.
