The original website that revealed all this has been updated. They have found many of the images from this photographer have stock elements. Which in general is fine if you want to use them for commercial work etc, if you have paid for the rights to use them. However when you look at the website and they show you some work with links to its wins, and then show the rules for the competitions it was entered to, then the rules of those competitions have been breached.

The original website has now found several stock images that have been used repeatedly by the photographer in competition winning entries.

Just scroll down a bit to see all the new stuff: http://stopstealingphotos.com/

About 1/3 of the way down there is a heading 'Update 2/7/2019 @ 7PM / 11PM' and all the new stuff is under that.
