Drawn in Inkscape. Clear messaging not to proceed, yet a bit subtle as it doesn't have "NSFW" or any other indicator that explicitly identifies the type of linked content. An intense red circular frame for attention getting filled in deep red with a hand in the universal stop or halt position in the center.
