I received a junk email that was directed to wikimediaro-l-owner@lists.wikimedia.org. To the best of my knowledge, I'm not a list owner or list memember for Wikimediaro-l. Checking https://lists.wikimedia.org/mailman/listinfo/wikimediaro-l suggests that there are no list owners.
There appear to be at least two mysteries. Why are there apparently no list owners, and why would email sent to wikimediaro-l-owner@lists.wikimedia.org be sent to me?
