That's a great question. In this situation both words are correct. His photo is in the thumbnail which is misleading because he is not actually in the video. That makes the thumbnail, "click bait". I also used him as click bait in the title and video description. "Baby Brother leaks trailer for The Quest 2" ….he is only 4 years old so he didn't really leak the video. In the description of the video I asked the viewer "Did Fancy's Baby brother really leak the video? Or did we just need a reason to put this adorable little boy in the thumbnail?" hope that clarifies why click bait was my choice of words. If not here is the actual definition...
Clickbait, a form of false advertisement, uses hyperlink text or a thumbnail link that is designed to attract attention and to entice users to follow that link and read, view, or listen to the linked piece of online content, with a defining characteristic of being deceptive, typically sensationalized or misleading.
