I just had someone post a comment to the ACTIVITY STREAM. They had no username or avatar that I could see. When I clicked the VIEW link it resulted in an endless redirect loop. Bug or intentional hack?

This is the comment, user doesn’t have a username or an avatar – http://i.imgur.com/7giSv.png

This is the DB entry. Note that the user_id is “0”. Yet when I check wp_users the lowest user id that I see is my ID… the admin, which is “1”. http://i.imgur.com/iUZGq.png

This is what appears in the URL bar at the top of the browser… I stopped it, but eventually it crashes and I get a redirect loop message – http://i.imgur.com/7LWYF.png

Capture of wp_users ordered by lowest to highest value. Note that “0” doesn’t even appear – http://i.imgur.com/dfnCS.png

Anyone have any idea what the problem is? I ended up logging in as admin and just clicked the DELETE link next to the comment in the activity stream

Ignore the last capture. That refers to ID which is another value.
