Hi,
There are many 'tweaks' floating around that really don't improve security at all and create a lot of incompatibility and problems. This is known as security through obscurity - trying to hide things - and it isn't that effective. Particularly in this case because if you view the source of your home page you'll probably see all kinds of URL's that clearly display where your wp-content folder really is.
Also there isn't anything in wp-content that should be vulnerable if you're running a site with everything upgraded.
However I've noted your comments and that some people choose to do this so I'll see if we can detect where your wp-content is and add that to the falcon rules we add to .htaccess.
Regards,
Mark.
