Post Made Community Wiki by Community♦

Why did this occur?
It appears that long, long ago when a user ticked the "community wiki" checkbox on their post (which can no longer be done for questions), it just got attributed to the Community user rather than listing their name for it (or maybe they didn't get recorded at the time and are just now getting attributed to Community). This is also demonstrated by this community wiki question which was made community wiki by the author the moment it was created.
