What a wasted opportunity. They have a good, linkbait worthy title yet
it looks like there's not a single actionable link back to their search engine. Upon closer inspection, the links are there (they are the images) but as a reader, I expect that when I click a link labeled "Click image to expand", that the image gets better. That's not what happened - I was taken to the page showing the search. Why not just have the link to the site visible and easy to see?
I'll let someone else talk about the tongue-in-cheek attitude of "Our search engine is what you should use to do harm to others. We think that's pretty cool and want to encourage you. Here - have a tutorial that will make it easier for you!"
