On Tumblr, there isn't a built-in feature to hide reblogs entirely, as reblogging is a fundamental aspect of the platform's content sharing and community interaction. Reblogs allow users to share and spread content across the platform.
However, if you want to minimize the visibility of reblogs on your Tumblr blog, you can consider the following options:
1. Use a theme that displays posts in a more compact format: Some Tumblr themes offer different post styles, such as grid or list views, which can make reblogs appear less prominent compared to original posts.
2. Customize your theme: If you have knowledge of HTML and CSS, you can modify your Tumblr theme to adjust the appearance of reblogs. This may involve reducing the size or prominence of reblog information or altering the layout to make them less prominent.
3. Add a "Read More" tag to long posts: If you add a "Read More" tag to your posts, it will truncate the content, showing only a preview until readers click on the post. This can help minimize the visual impact of long reblogs on your blog's main page.
Remember that Tumblr is a platform built around sharing and reblogging content, so completely hiding reblogs may go against the nature of the platform. However, the above suggestions can help minimize their visibility on your specific blog.
