This demonstration is not authorized and is in clear violation of Mall of America policy.
Those who continue to demonstrate will be subject to arrest.
For not more than a week (probably just a couple days), I have consistently seen the "BGG is down; addicts go elsewhere" page whenever using the back button to go to the main boardgamegeek.com page. "Back" works fine to get to any other page on the site, and navigating directly to the main page is also working.
I'm using the latest version of Safari on the latest version of OS X. Under Opera on the same computer I don't experience the issue.
