I suspect you are showing us the robots.txt file for the link that is blocked. robots.txt files vary per site. In this case https://static.doubleclick.net/robots.txt.
doubleclick are themselves saying, don't crawl our site. That is fine as Googlebot is not interested in ads. Quite a few third party tracking systems will do the same. It's nothing to worry ...
