It’s been brought up a few times, but I don’t think there is a topic dedicated to it. There is a topic on Feverbee that I contributed to: https://experts.feverbee.com/t/is-it-possible-for-the-feverbee-blog-posts-to-be-pulled-in-full/6192. It is possible to set the Canonical URL of a WordPress post so that it matches the Discourse topic. Beyond that, I don’t think there is anything the plugin can do about the duplicate content issue.
