If you look at the very top of the source, you'll see a line that says (angle brackets changed to curlies) {script language='jscript.encode' src='/root/%61%64%73.php}{/script}. %61%64%73 in URL-encoding spells out "ads", which is what this is doing; it's trying to set a popup. I think this may be what hostalarm's complaining about.
However, that's not why your downloads aren't working -- it's just that hostultra's doing referer checking.
wget http:/pre> //www.hostultra.com/~AngCobraFics/atotw113.txt
gets the "oops" page -- which claims to be a 404, but isn't -- but
wget --referer='http:// www.hostultra.com/' http:// www.hostultra.com/~AngCobraFics/atotw113.txt
downloads the story normally.
