To address the above bullet points, won't you need to clean up some of the "Main (copy) (copy) (copy) (copy) (copy)" entries?
I would think something like deleting ">10, not accessed in 1yr" racks would be acceptable.

That's always a little problematic. Many of the racks screenshots are embedded in forums. Deletion would result in a lot of broken images which does not look good.
I delete older empty racks and unused anonymous accounts though.
