I have a hub that I add some external links to my other blogs. This message appear "Please address the automated warning below before submitting this Hub for publication. Please click on the warning to learn more. WARNING: Too many product listings Please address the moderator set alert below before submitting this Hub for publication. Overly Promotional: This Hub excessively promotes products or another site This Hub needs to be revised before it can be published." I already removed all the external links and submitted but HP still rejects it. How do I delete this hub then?
