When you search for the private equity investor, John K. Castle, in Google, you will see a knowledge panel on the right hand side. Give it a try, search for [john k castle], the issue is, the image of choice there has his picture with red writing on top of it that that says "You Schmuck!"
Here is a picture of the Google search result as I see it right now:
The image is being pulled from a Gawker story about the investor.
A man named Jeremy Woods asked why this is happening and posted it on the Google Web Search Help forums. He wrote "I have reported on the issue of a profane image showing in the knowledge graph twice already - the issue was resolved both times, albeit temporarily - but now the same problem is back once again." "In addition to helping me solve this issue, can somebody recommend a way for me to stop this from becoming a recurring problem," he added.
I wonder if some SEO has a problem with Mr. Castle, I mean, why would the image keep coming back?
