I was browsing a user's profile and clicked on one of their posts under "Top Network Posts". It was a question, since the path of the URL of the post did not end with a numeric post ID.
The OP of the question showed up as "anon". I am not familiar with what happens after dissociation, but this made me guess that this is a post of this user who has dissociated it.
I am not including the profile of the user for the user's privacy. Let me know if I need to provide it.
