Meaningless error on drupal.org homepage

I'm not sure where I should post this. Please feel free to move it.

When I opened drupal.org, I got the error "The username DavenMichaels has not been activated or is blocked". I don't know whose id this is, but it showed up on my browser, when I visited the homepage. Also I was not logged-in. I'm attaching a screenshot. I'm guessing, it is some sort of cross-site scripting bug or something..

Btw, I was logged-in to drupalgardens at that time.

Thanks!
