No, you weren't being overly harsh. I would have voted to close this as not a real question or too localized.
The Re-open audits are kind of strange though. Unlike the others there's not always much obviously wrong with the post. However, a re-open vote is something that cannot necessarily be assessed in seconds. It's something that can take time.
With the newer changes there's a revision in another tab. Where this doesn't exist and there's no comments indicating why someone voted to re-open you should be looking for both the reasons why it was closed and a reason to re-open it. This normally means you go to the question page where it becomes immediately apparent that this question is already open.
There are certain clues that this is an audit as well. It's a recent post, with a fair few upvotes. If it were an older post it's likely to have been closed as not constructive if it's in the re-open queue and has upvotes. There's an audit "smell" about it.
