Could this happen if the parent or child got hard deleted?
Also a couple of cases where the parent/child gets wrongly removed as happened with post #1056096.
Or the tag could just have been added by mistake (including one slightly bizarre situation where the post had been parented to itself).
The fact that basically all the duplicate parent:none child:none posts have/had (I got rid of a few) different people causing it suggests that there isn't anything malicious going on here.

Try duplicate parent:none child:none status:active order:score. Also note that status:active filters out status:banned; you probably want -status:deleted.
