I've already created a ticket with Zendesk with this request and it came back negative. I can create a report in Explore that allows me to see all unverified articles with the title, id and author but that is not what I need and also, just not a relevant report.
First of all I believe it is very strange that I'm only able to get the Author of an article when it comes to the verification feature and not the Owner since it is the Owner who is responsible for verifying the article and not the Author so the author attribute is useless in this case.
Also, without the attribute to see how long ago an article has been verified for the last time, I don't see a use case of creating a report based on unverified articles. A list I can see in the admin centre of the guide, but I need to have reports.
Speaking of which, you can see a nice list of all unverified articles with all the information I need (when the last verification was, title, owner, etc) but you cannot export it or translate it into an Explore report.
Kind regards
