Not sure if I quite understand why. It could be the 'overly promotional' flag?
Another option would be to 'group'
the majority of your hubs are in the same niche and you could group those together. The group feature is in the same section for tags, setting, summary...
Group is the feature that pops out under your voting boxes. It is a green divider and has arrows to the right and left. It features links to your other hubs. You may have seen it on some hubs. It's an optional feature.
Hope this helps
