Is this definitely not algorithmic? I&#x27;ve been noticing for a while that videos might have an incidental flash of cleavage and then that is used as the thumbnail. I&#x27;d always wondered if this was arising &quot;naturally&quot; somehow (people pausing that scene perhaps?)<p>On the basis of the type if video I&#x27;d discounted manual intervention. Though if people can just upload any image I&#x27;m now surprised that they&#x27;re not all like this.
