Go to the person’s Tumblr page. Copy the person’s Tumblr username from the beginning of the page URL. For example, if the URL in your browser address bar is “johnsmith.tumblr.com,” copy the username “johnsmith”. Delete the URL in your address bar and replace it with “www.tumblr.com/liked/by/username" without the quotes. Replace “username” with the person’s username. Press “Enter” to view the person’s liked posts. If you get a “Request Denied” message, it means the other person has made his likes private.
