Scott,
Someone on a domain is running joomla. On a logout they get 403 errors. I have attached the audits. At first I saw user=Administrator, I got them to change that as I thought that may trigger as its a bad name to use.
This was still using the user Administrator:

Now using another user, you will see there is no admin name, but it triggers a hit.
