Thanks. I think the most likely is 2), a poorly written spider. I'll ignore it for now. I only made one symbolic link for one file. Somewhere else I have a text article that has the URL. If people read it offline and then decide to go to the URL by manually typing it, they could be lazy to type somefile.html instead of SomeFile.html.
