This was a dupe from an article posted 2 days ago. Not sure why it wasn't detected.

This is a dupe of something submitted earlier this morning. Was the original deleted for some reason?

Huh, how did that get past the dupe detector? It's exactly the same URL.

you clearly know this submission is a duplicate, please don't copy-paste the same comment to all of them. Link the previous & flag instead please.
