Because the pictures are bizarre. Take a look at the one I linked to - his chin line merges with his neck. The bags under his eyes are weird. He looks like he is added on to the background. And the background itself is super weird.
The other one that I think is generated is the picture of "Pop culture critic Ian Williams". Gillen's is ok.
> I did a reverse image search just to double check, and the only existence of the photos are on the cbc site.
The reverse image search didn't return anything precisely because they are generated. Search for the other image - that of the writer Kieron Gillen. You'll find it.
