As you review the potential articles in the external blog library, you may decide that some aren't right for your stakeholders. If this is the case, follow the instructions below to ignore an article and remove it from the default feed.
From the Import External Blogs screen:
Hover over the article you'd like to ignore, and select Ignore This Item
That's it! This will remove the article from your default listing. If you accidentally ignore a post and want to bring it back, you can do so by following these instructions:
In the top right hand corner, expand the Screen Options tab
Select the checkbox next to Marked as Ignored under the Also Include Items title, then hit Apply
This will add articles that you've previously ignored back to your default feed!
