This is quite old (it has been sitting in my to-do list for a while) but still fun:
When I looked at the screenshot I saw the peculiar structure towards the top of the page (the first "script" block) and did some searching around. It turns out that this structure is added by ad-blocking code present in some Symantec products as documented on their website. This means that probably whoever made the screenshot at Sunbelt was using Symantec’s AV on their system. Interesting to know :-).
