Once you publish your article on your blog, we display the article on Hashnode feeds for more readership.
If you want to hide the article from the Hashnode feed, you can do so before publishing by selecting the "Hide article from Hashnode feed" option in your draft settings. If the article is already published, you can edit it and choose the same option in the article settings.
Your article will now be hidden from Hashnode Community feed page and search results.
