This is was probably a user that either wanted to be deleted or broke the rules at some point and the team decided their previous non-spammy posts still might provide value to someone.
I have no idea what happened (probably something similar to the above issue, but something went wrong with the database), but thanks for bringing it to our attention. These should be fixed now.
No problem. I double checked these from different sources, and all bore the same results. Thought something was weird with my account for a second - phew!
