Since all the sites I own / work on are Yahoo! Stores, HackerSafe can't really test this stuff, or if they do and find anything, I can't really change anything because Yahoo! takes care of all the IT heavy lifting stuff. I should have posted something about this to clarify my original post.
However, my rep at HS said that they actually do test the entire Yahoo! Store Platform for Yahoo!, but they just can't take credit for it for some reason.
