Just for fun, I decided to do a Google search of one of my photos.
I found it on the Forbes.com website with no Alamy (or personal) attribution. This article is date May 20, 2013.
I did find a sale on Alamy that sounded like it could be this, but the usage is for June 2013-July 2013 for a print usage in a North American magazine with online archiving of the article. Is there a way to find out from Alamy whether this sale was to Forbes? (If so, can't believe it's $50 for a print usage in such a big magazine, but that's another story).
Does Alamy require Alamy attribution for photos? If it doesn't say Alamy, is it likely a theft??
Any advice on how to proceed would be appreciated.
