@matrix_jan Thanks, I can understand why it wouldn't help - it was wishful thinking. I have just banned BingPreview as a UA because they are not just requesting images, they pull the whole page with all related files. It keeps the bing IP so I don't want to block that but I have had to disable AdSense because other links on the page indicate (nonexistent) clicks whenever they request a page. The links do not normally set a cookie from viewing the page, but they are when shown via BingPreview. They are making nonsense of my stats.
