There seems to be many accounts that were created with the intent to spam, but that never did.

They are doing their job though, accounts each have their own page, these are indexed by Google which will increase the page rank of the linked page.
Perhaps the simplest solution would be adding the user pages as not being indexed in the robot.txt.
