"Legions of viewers add me or my images to their 'favorite artist' and/or 'favorite image' lists without actually commenting the images per se." And how many of those legions of viewers are adding you to their list to later steal those images for later use? Adding you to their favorites list is one way to easily find the image they want later instead of scrolling through tons of images to find the one they want or having to do a search for a particular atrist.
