Thread:Support/About MediaWiki:Flow-moderation-intro-delete-post/he

A few days ago I suggested adding dummy GENDER with $1 to the English version of this message and others similar to it. Now it became even more confusing: the qqq says:
 * $1 - (Unused) the name of the user whose post is being deleted. GENDER supported.

So is it used or unused? If it's used, it should be something like "Please why you're deleting this post."
