I just got this e-mail from Feedburner:
I’m afraid you may have quite a serious issue on your hands. Every page
on your site from your front page at http://www.samuraisoapbox.com/ to
your very first article at
http://www.samuraisoapbox.com/2006/06/27/thank-you-nathan/ contains a
very large block junk links appended to the end of every page. Do view
source in your browser to see it at the bottom of everyone one of your
pages. Your feed is no different and has this same block of junk added
to it, making it invalid. I’m afraid your wordpress installation may be
hacked and that is what is adding this junk to all your pages. You
should contact your hosting provider and/or wordpress support immediately
to work with them on removing this junk from your site.
Please help! What do I do??
